Really nice game!
it has a neat concept, the art is astounding! However I would like to take note of a few things I think makes the game a bit off.
-jumping might need some tweaking. It just feels as if gravity sucks you down the moment you let go of the button.
-There are some cases where the player is standing at the edge of a block or ground, but won't seem to jump
I think that's all i could say, however I have only played a while on the keyboard since I wanted to see how the game would work with controllers.
Overall, This is a really great game! I would love to see more levels. Maybe a walljump mechanic might be a good idea idk. But good job dev/s!
