I love Tower defense games and I think that with a little polish this game would be excellent.
I found out early that you could stack towers on top of each other which meant I could make a giant death tower stack in the center of the road which made it easy to death the shadows, so stopping stacking would be a nice QoL
The artstyle is very nice and consistent really enjoy the shadows, the big fella with the seven eyes is my favorite.
Cheers, hope to see you next Game Jam.
