To be honest, I struggled with this one. The controls were not well explained and the text was too hard to read. I think it would benefit from some sort of tutorial, or even just an explanation in-game on how to actually play. The starting is a bit too hard - I think the progression should have been quite easy for the first run, and then ramp up the difficulty with different enemy types and the ability to upgrade the turrets. Maybe those are in there and I just didn't make it very far - I'm pretty bad at tower defense to be fair.
The hand-drawn art is cute.
