This is a really fun game that although unpolished was a great idea and was pretty fun to play. I actually got hooked for a long time and ended up on the leaderboard. One thing that i need to complain about is that the turrets should be shooting at the closest enemies. Near the end i got killed by the enemies because the turrets were firing at enemies that were very far away and were not a threat to me. Also probably make it easier to place things as it gets tiring dragging them when in the lategame you float lots of money and need to defend.
