RatTower couple of things only, since I don't have time to argue about game design:
1. no graphical settings on the main menu, only when you enter the game - I would recommend you add them and rename them from numbers to descriptive words (low/0, medium/1, high/2, ultra/3)
2. not sure if the settings are even being applied (tried lowering all settings from 3 to 2 without any improvement), I get huge performance drops on AMD3600/GTX1080/16GB RAM on 1080p from 60 to high 30s in the corridor where you meet the first zombie or whatever (needs to be optimized)
3. consider implementing AMD FSR as well
4. when looting things, you have to use the mouse and click on Close - clicking something on keyboard (Esc, C, X or whatever) should close the window as well
5. characters are too small, consider implementing font selection so reading letters will become easier to people with shitty eyesight (read: me)
6. using torches to light some things says I should press <M3> - not sure what that is supposed to mean (also not sure if having a gamepad connected might be the underlying cause behind it)
Good luck with the kickstarter, I will write more impressions/feedback in a week or two if I feel like it.
