Here is some more constructive criticism. One thing the is needed (besides money given to you in the beginning based on your last score) is more money as the zombies get harder. The controls are also so slippery and inefficient that zombies with rotting muscles are able to catch you. the character aught to have at least as much mobility as the them. other then that I realy like the idea of the game. It just has some idea flaws. Of course on low mass objects you would have trouble moving but not that much trouble. in a way you would be faster.
I have been working on a squeal incorporating everything you mentioned (slower zombies,more responsive controls,increased focus on upgrades and a working loader). its still in development and nowhere near finished but any feedback is good feedback

it really needs a way to be more of an upgrade thing and can at least make the zombies become more powerful slower and more numerous slightly slower it really needs to be able to keep money you die with and at least 1/4 the money your guns were worth
The memory system is very touchy and i didn't even touch the clear history thing since i started playing. idk but somebody should look into it. not too important tho
