I really love your game, honestly it's the best I've played in this jam! <3
At the beginning we think it's a simple platformer but finally it's so much more intelligent, really well done!
You really got me with the first vertical bar, I tried it at least many times, I even thought the game was bugged, and then when I understood I said to myself "it's too smart!"
I don't know if it's intentional or not, but when the game is reversed, you can't see the whole game anymore, the bottom ( or top... ^^' ) is missing, so for some levels it's a bit complicated :/
And one last thing, it's really a sad that there is no full screen mode because the void atmosphere is very cool!
