Fun game! feels like Hotline Miami x cod zombies, I felt like I was having a easy time until wave 20 then started to get swamped and performance suffered a bit once I had a lot of enemies in a train, died on wave 23!
I think the map layout was nice good for running enemies around but still giving chances to get caught out if not careful. I wish the top weapon buy was a tiny be further from the window accidently bought it twice trying to repair. I love spinning the box for weapons gives a good feeling of nostalgia just wish there was some sound effects, it would be nice for the box to close for reroll after a bit if you get a weapon you don't want.
I would also love some audio to hear enemies breaking in or running up behind me.
Overall very good job! clear straight forward gameplay and fun variety of weapons.
