There are two bugs that need to be fixed. First mission 11 "Island" has you able to build on the spawn points of the zombies, thus making every enemy except for flying ones useless. Second mission 12 "Finale" spawns me on the blue power marker thing's ledge, unable to move. This didn't change after restarting the level multiple times and it made the level impossible due to invisible monsters being able to steal the cores without being able to stop them. The first should kind of be fixed due to how trivial it makes that level, the second should definitely be fixed.

Other than the flaw of being unable to actually complete the game, it was fun.

very fun game 5/5

I really like the amount of upgrades that you gave for us to try out. Over all a good tower game.

Fun game. I like that we have the option to level up our towers or the main gun, adds a little replay I think. Nice work.

Great game overall. Flyers were a bit of a hassle at first then realized I only need to block one area. I feel like that it needed a little more difficultly because I beat this whole game using only two different towers and leveled myself up in the process.
