Pretty cool game even if a bit too hard for me, and this comes from someone who's used to playing retro shooters on high difficulties. I think it needs some balancing, imo:
- Melee enemies are way too fast.
- Enemy AI for normal and big baddies is kinda meh, they seem very dumb. Try to have them have better reaction times and pathfinding and it should be much better.
- The pistol really sucks, not very fun to use. Could it have just a bit of a higher fire rate?
- Introducing multiple new enemies in the same room and having some of those lunge at you at high speed is not a good design choice imo. Makes it so either you know the level by memory or you die.
- Since everything is grey, I had a bit of trouble spotting the shotgun.
Now, onto the cool stuff:
- I liked the music.
- The shotgun, it feels punchy and it's quite nice to use. The spread is, imo, as it should. Very fine weapon.
- Level design made sense to me. Never felt lost or like I needed an automap.
- I like the tone and humor. Having the tutorial being some posters for the enemies is a cool idea.
- No hitscanners? Nice.
Overall I had some fun! I've uploaded a video of one of my playthoughs:
