I like that you can actually build the level, very nice tweak. 

I don't know how long it can get but I just build one or two block at a time and went on the same height for over a minute. Then I didn't get the timing right. I think because of the particles being randomized, you can just stay on one height the entire time. 

Overall very good polished entry!

Maybe add some kind of leaderboard :)

Really polished game and the concept works pretty well too. You hooked me with it :) 
I've founded the way to stay alive an infinite time so if there is one only change to do :  score with the distance instead of the time. :)

I like the minimalist aesthetic, great job.

The game is way too hard for me, consider making it really slow at the start for players to get used to the game and then make it faster and faster the further they go.

Good Job with the jam!! Well made!!

Quite hard ! But well made :) I liked it was not just a "move the environment" game, the more challenging approach elevated it 

Little bit hard, but I like it!

Tough game, and very nicely done! Reminds me of Geometry Dash

Very cool game! 

Pretty cool concept
