This was an amazing experience, slaughtering civilians just to get better upgrades? Awesome.
I really applaud your CLEAN game loop! Not many people can achieve a game that very nicely loop when you die and begin again, and is still fun. I also appreciate that your upgrades stack, nice touch.
The graphics, man this is SO COOL, i've tried a 2.5D style once in a jam before, but got nowhere as near to perfection as you.
Also, my game got bugged the second time and nighttime never occured xDD so new civilians just kept spawning in and giving me their tears to feed on, and I got the best upgrades ofc.
Amazing job tho, you've got a good chance of winning this.
