Very cool demo (4.1)! I hope you'll keep going because it's pretty fun! I couldn't find all the controls (didn't know if I had items) but I figured out R was reloading :P I also hope that there will be an option to turn off texture filtering/blurry textures. That is, if the textures themselves weren't already blurry :) I also felt that moving around felt a bit stiff and if I stood still, I had to toggle run again. Also after running for a little while, I felt like I was slowing down (like faster than walking but slower than running) but that might just be me. Keep up the good work!
