I enjoyed it, almost done 5th wave on my phone, btw. I think you can improve it by adding handling second (RMB) attack on mobile. I really loved design, it's really nice, but didn't understand why hp bar wasnt in same style as game. Also wanted to say, that balance is smooth, I didn't have difficulties and at the same time the game challenged me. Thank you for done work!
Will be glad if you try my game prototype too.
