Very pretty aesthetics, loved the pixel art, loved how it gets dark and the music changes at some places, very awesome.
I didn't feel like there's a progression curve tho, 30 seconds in and I was already stuck at a big fight against several zombies.
Thx.
Doing it again I would design the levels differently as to stop people from potentially going straight to the second area with out any experience in the first. A friend who play tested the game also did something similar.
