Heya! I found this game after you left a comment on my game; Fading World.
This game is super well designed and simple to pick up and play. I feel that it is ripe for expansion to be honest :)
I have come across a couple of bugs... One allows you to cling to walls when you move into it while in the air, and another lets me hop on the lava if pressing the jump button at the point of impact.
Good game though, with a great implementation of the theme!
