This game seems like it could've been a lot of fun, but the start seemed rather confusing and unbalanced. It felt like more enemies appeared than your starting towers can handle. They'd die, but not give enough money to buy a tower before the next passed the tower on cooldown so you die over and over until you get a good pattern.
The game's great outside of that though. The simple art style is very charming and I loved the transition between the start screen and the actual game, and the one run I had where I didn't die instantly I had a bit of fun.
Overall still good, but needs some polish.
