Hi! Just wanted to point out a bug I ran into, when you are "revived" you can generate in a closed area and your game becomes unwinnable - see below.
Also I really like the tiles and art style, but the glitch effects are really disorienting once you get to the level where you "lose signal". One of the effects even offsets the screen by an entire tile-width (also shown below).
Overall the game was pretty nice though, would be great to see it with more enemy types and overall variety :-)
