Firstly- my current record is 11!
Secondly- my opinion about this game went from "this is gonna be annoying" to "this is pretty difficult, but has surprising amount of depth" in few rounds! I like how, even when you throw your glasses, there's a small effect when enemies spawn. I like that, even in just a few rounds, I started to try out new tactics. I like the presentation (graphics and sound) that go for the mind 90's retro feel, and nail it!
Hell, I like the way you used glasses in your game, and that it's a kind of a street fight!
There are just two things I'd change.
1. It would be cool if there was... more! More enemies, more weapons, more levels. If the endless mode was an additional thing.
2. Autofire on the gun would be sooo nice. I'd prefer to hold the mouse button, than clicking all the time, especialy, when there's no ammo limit, and there's almost no point to not be shooting most of the time :)
