I feel like this game was rather rushed. There is no real objective to the game (No exit to the maze).
The zombies look horrifying, not because they're zombies, but because they are not layered properly. The zombie AI is pretty good but they move a little fast for their animation, and there is one zombie who is always stuck at a specific spot and can't move.
The art and music are ok but the walls of the maze could have used some textures.
Overall I think that if you maybe had an artist teammate, and a bit more time, you could've really improved this game. Good luck in the jam!
