Really fun horde game, with an interesting twist to keep you on your toes. Sound design is great, that audio system you used worked a charm, although some background music would've been nice also. Also, I noticed in the later waves the humans stack on top of each other which means you kill them too easily- although I was playing in the sim so it's likely I had an unfair advantage haha.
Art is also great, and I love to see people use Noble Engine. Congrats on the first game, it's a banger!
