Better luck next time...
This has the potential to be good but is only a work in progress. Playing the game is tedious and frustrating as it is unresponsive at times and the reload is too quick. You can keep shooting with about one second of reload time. Enemies deal small amounts of damage to your base giving you time to shoot them without losing a great deal of health. The only tip to play this game that I can give you is to buy lots of tower guards.
