The game was pretty enjoyable. The art assets were good (you should credit them) but some of them were unrelated, like having pyramids in a green grassy map, which made the game feel a little incohesive. The sound was good but there was no music in the game.
Gameplay wise, the game is a simple third person shooter. The camera location is very weird though which makes controlling the character quite difficult. The random map generator is cool but sometimes it generates some weird levels (rooms clipping other rooms). Also, i don't really see any difference between the difficulties.
There is a pretty big bug that I found where, If you have the vaccine, you can keep curing an already cured mummy and it will keep decreasing the infected counter.
A good game that could have been better with a bit more time. Good luck in the jam!
