I finally got to play the game! Sorry it took me a while :(
First I would like to say thank you for reaching out! I thought that was very cool.
Second, I love what you're doing with the game! It's really fun and it runs smoothly (guns reloading animation and sound effects is a nice touch). The zombies (or infected?) have cool designs and animations ( I like how some run, walk, alert others etc). I do wish there was more variety of enemies (possibly big muscular monster similar to the tank in Left4Dead, jumpers, crawlers etc).
Third, I wish there was stacking for certain things like bandages since it's essentially cloth which can be compacted BUT if you're are doing that intentionally its fine~ I also would have like an option to drink/eat things without putting it into my inventory first to use it.
Overall, Idk if I missed any points/ forgot. All I can say is that I loved the game A LOT and hopefully it gets a lot of recognition it deserves~ I can't wait to see more from you :)
(Sorry for long review lol)
