i spent too much time replaying this until i finish it x) was alot of fun
+ weapon mechanics are great. timed reloads add a ton of depth to the game
+ well balanced difficulty, i always felt like i was "on my toes" while not feeling the game's unfair
+ wave reordering is a really cool mechanic that could be expanded upon
- i didnt know that i could use MouseWheel to change weapons, the HUD didn't indicate i could hold numerous weapons. i thought that when i'd buy a weapon it'd replace my previous one, so i got stuck a few times thinking i ran out of ammo even though i could switch guns
