First Godot Jam joined? This is very decent for a first submission! The retro/vaporwave style complements the overall blocky look and keeps the game visually interesting, and the mechanics are solid!
Will you add any way to download the game though? It's really laggy on my browser, and I can't enable hardware acceleration unfortunately. Due to the lag, I can't enjoy the game as much as I probably could've on a smoother playthrough. Still, I'm sure the rest of the levels (I've only played the first 4) are good. Well done!
