Wow, this game has crashed twice on me so far. Once yesterday and then again a few minutes ago today. I was well past floor fifteen; nearing floor thirty or so. I was at least level 60... I get no titles at all because it crashed instead of me dying. :/ This is a pretty severe bug that needs to be fixed. Currently the game is too unpredictable to continue playing.
An okay game but it needs some work. Being unable to reduce the quality I found I lagged... A lot. By the 20th wave I had the left room filled entirely with turrets while I ran around the right side of the building shooting things in the face... More run speed would've been nice. A bit more stuff to upgrade would've been nice as well. By the end of the game I was rather bored because there wasn't much variety or difficulty.
