Awesome work man :) ! After watching your making of video I was looking forward to trying this out !
Visuals are simple and nice and the music/sound effects are really neat. I didn't feel like there was that much strategy involved for the gameplay, it was mostly just wait until I have enough coins and place a turret, so I got to wave 8 or so I believe without any real challenge. But still, it was a pretty relaxing experience, one that fits very nicely with the theme of the jam.
So yeah all in all well done and keep it up :) !
