Treacherous Trials
UPDATE SEP 2026: A new campaign has been added! Can you survive 5 longer, harder, and much weirder levels?
This update also adds save data, a proper settings menu, redesigned character sprites, and much much more... I need to rest
===========
A short game made for @LoafeeBuns' birthday, based on their Geometry Dash inspired personifications and lore. Original game made in 10 days (Sep 2022), with extra content taking... longer than that.
The extreme insane moderately tough (but very handsome) demon Nine Circles is undergoing some intense training! Can you help him master his abilities and survive the countless trials he must face? Who knows?

It was a challenging game, but I enjoyed it because it was manageable if you played carefully!
The X stages are even more difficult, but the checkpoints allow you to quickly recover and keep trying, which is great.
X5 was tough because the checkpoints were far away, but it was more enjoyable to complete.
Personally, I felt the falling speed was a little fast, making it almost impossible to improvise after seeing what happened. I found it particularly difficult to deal with things using movements I had memorized beforehand, but that made the feeling of satisfaction when I succeeded all the more rewarding!
Also, after playing this game, I felt like playing Geometry Dash again after a long time, and I discovered that it has tower stages!
It's Geometry Dash, but it's a platformer and has the same save points as this game, which made sense!
glad you enjoyed it!!! i agree that the fall speed is too fast... it's something i would have changed if i didn't lock it in so many years ago.
thank you so much for the video, i enjoyed it a lot 🧡
i decided to keep the original 10 levels completely unchanged, as a little time capsule for myself :)
i like it alot lol, treacherous trials is one of my favorite platforming games :)
i wanted to say this was good challenging game. but what the hell is this part?gap between jump object and spike is so narrow i have to press dash button twice immidiately then guess what. character goes left of screen too much i can't reach platform on the middle. i tried this part over 500 times succed only once. this part is worst design i've ever played entire 20y+ years of gaming life. christ i have no words to express my hatred of this part
nevermind i cleard all of stage whatever
*angry unc over here (not me btw)
This game was awesome. I loved the level design it really put my brain to work.
Felt super satisfying to beat lvl 10
I've completed it and keep coming back to speedrun it. The classic levels are so damn good. Never seen level design of this level,
Nice game, in teresting idea with the switching!
I would improve the jump animation and range,
maybe also allow to do the switch in mid air can be interesting!
(check my game too if you have time :D I would love some feedback)
rất hay nhưng nếu các phím có thể tùy chỉnh theo ý muốn thì sẽ rất tuyệt <3
holy gd refrence, nine circles
Its literally colon from geometry dash
i didn't know gd colon was involved but ok
cool ig
Cod3breaker was brutal (took me 52 minutes LOL) and definitely a step up from Slaugterhouse, can't say discovering how to approach it wasn't really fun and rewarding, though!
My only issue (nitpick, really) is that the conveyor belts introduced feel wrong since it affects you even if you're in the air, but aside from that, amazing content update, and I had fun replaying throughout the entire game again!

Really good i love this game 🎮
WHY IS THIS POPULAR NOW?
i love gd cologne
Incredible but incredibly hard asw. Great job man!
Really good game I like it
very fun and gimmicky extra levels! i really liked the sections where you bounce off the swords using the wave. can definitely see the sj inspiration on these
new levels peak but also dang they're hard
this is really cool i like this game and i like gd cologne
i think this is really good, but it has a few major flaws. first of all, the gravity gets far too high exponentially fast. it's so horrid, it's almost impossible to aim at things correctly when falling. that was definitely my biggest cause of death. also, sometimes the dash key just doesn't work. i noticed this quite a bit in level 8.
i love gd cologne
Forgot colon was something of a programmer himself
gd type game
i loooooove gd cologne
hi furry
W
This is a good game :) (also im youtube subscriber)
w game
my bruddah in chart I'm going to throw my phone at the fucking floor if I can't beat slaughterhouse on mobile lmao
Is this some sort of... geometry jump game?
I got 37.440 on demon moment. I'm sure there's a couple tenths to gain to that. I think a 36 maybe high 35 is possible.
level editor please. doesn't need to save levels if that's too difficult to code but it would make the game infinitely more replayable (i beat the game 3 times now and i love it)
beat the game 5 times now lol
finally beat it 10 times
you are frickin cracked
i loooooove gd cologne
cool, search me up on geometry dash (greedygrey1234)
Are me and cologne that different? We both play funny cube game, we both like singing robots... wait that's kinda it.
nine circles
APK?
no
Lyrics of Geometry Dash Gangster Rap by Boom Kitty
verse
Yo guess who′s back with the rap debut
It's ya boy Boom Kitty with the GD crew
Got the sick new flow with the bass down low
Back on the top of the charts since two point two
No matter where I am: on the go, in the car
I′m always on the grind, and earnin' my stars
I've been a GD chad since I was a wee lad
First bringin′ the bass, and now bringin′ the bars
E to the V to the Dub, that's me
I′m so tight with Rob, he gave me two point three
You have more hair, but I have more demons
And I keep my cool, while you can't stop screamin′
1 mill subs on my YouTube brother
One of them's your sister, and another is your mother
Nobodies always ask if they wanna collab
That′s it, I'm out, to the recent tab!
chorus
All the GD players put ya hands up
All the GD players put ya hands up
All the GD players put ya hands up
All the GD players put ya hands up
verse
Yo slow down cuz the king's in town
You gonna trip on that spike when you see my crown
Not just better than you at the Geometry Dash
But the piano, dance pad, and even touchin′ the grass
When I′m slaying the demons, I unlock my flow
The chat goes crazy and they all spam GO!
You're beating the game, you′re on top of the world
Until I hit a back flip and I steal your girl
They say GD's just a game, but it′s how I get my dough
You better hide your coins, and don't overdo the glow
You call yourself a pro but you play on your phone
I spray bars on your girl, that′s why they call me Cologne
I'm a first-rate dasher, every vid is feature-length
My dedication's epic and my knowledge is my strength
I′ve been hella legendary since the game was in my hands
Now my mythical tales are told across the Dashlands
chorus
All the GD players put ya hands up
All the GD players put ya hands up
All the GD players put ya hands up
All the GD players put ya hands up
verse
When it comes to Dash music I am number one
Waterflame, Teminite, you guys are done
When a level drops and you hear a phat beat
Then you know it must be Boom Kitty bringin′ the heat!
bridge
All the GD players put ya hands up
All the GD players put ya hands up
All the GD players put ya hands up
All the GD players put ya hands up
outro
All the GD players put ya hands up
All the GD players put ya hands up
All the GD players put ya hands up
All the GD players put ya hands up
Boom Kitty has escaped
Repeat, Boom Kitty is now at large
Armed and extremely dangerous
i love gd cologne
