Castle Defend (placeholder title)

This is a game I made a long time ago as a school project, I changed some stuff to avoid using a lot inside joke between me and friends or using the actual names of real people. I also tried to fix every crash problem that I managed to encounter but I'm sure I missed some, hopefully not tho.

Build blocks to slow down the enemies and weapons to kill them, they destroy your tower, you lose.

So yeah, tell me how shit it is.
