Okay, so this game is not exactly beautiful. And I bet you know that. ;) But the levels are actually very well designed! And even though the art style is very minimal, one can easily figure out, which part does what in each level. I especially liked the white boosting block. Good work! Could use some comfort features though: pressing "R" to restart, so you don't have to touch the mouse. And automatic restarts if you fall out of the map. Also: Why are there only three crossed out blocks in the gap in level 1? Given that you only can jump once, you have lost anyway, once you reached that point, isn't it? I'm starting to nitpick here. Looks like you used the Godot engine as well? How did it work out for you? Did you like it?
