I kept dying on the height barrier as there was no idication of its location.  Also a bit explaining the game at the beginning would have gone a long way.

Hmm...not sure what you were going for with this one. Meaning, there's no "how to play" or instructions of any kinds, I cannot tell what/when I get hurt, and after trying a few times then the world flipped upside down which I assume is how ya'll interpreted the theme. The visuals are well implemented but the game feel needs some work to give better player feedback and at least a simple "AD/Arrows to move" and "SPACE" to jump would let me know that I don't have any other options rather than slamming all the keys on my keyboard to see what might happen next. This would help me wait for the "twist" when the level starts rotating :D

graphics feels a little simple, you can use some particles and lights, the jump can be a little better, but i like the gravity inversion , nice. i don't know how high can i jump.  i don't know if the game are really using 'rotation' theme.

Good idea, though i feel like a little more polish in the user interaction could go a long way for this game. The controls are tight, but the experience is a little rough otherwise.

This game needs a better indication how high you can jump. I kept dying on accident.

The infinite runner idea is neat but I feel the theme is a bit under-utilized. The flip is super jarring, and I think some sort of indicator that the screen is about to flip would’ve helped. Jumping is also a little buggy.

I can see that you've put a lot of effort into this one! Unfortunately it is quite unclear why I keep dying... I also feel obligated to inform you that the play button lights up when I hover over quit...

Overall a very good game!
