THe starting money is a bit low as well as the number of lives one has. To improve this game I think you should give much more starting money. It seems just like any other td game which makes this quite stale. One doesn't have enough money even to start the normal maze structure generally developed in such tower defense games. 2/5 until developer makes some changes. :)
You could add levels, upgrades, etc.
Also the controls are a little bit hard. I suggest making space the jump button.
Good job on your first(or second-idk) game. It's simple, but we done. :) 3/5
@aweso.... yes, everyone does near the beginning of the game. It shouldn't be too hard if you have bought a couple turrets. Just send it back or accept, the outcome is the same i think.
