I actually kinda like the idea of switching tower types, this changes the genre from slightly passive to a more active gameplay. There's one type of enemy that needed two different tower types to eliminate, I think that plays nicely with the mechanics you have and that's something you should build upon if ever you're thinking of expanding this ! Like units with layers of armour you'll need to strip away with different attacks.

Hey, thanks a lot!!!
Switching and avoiding artillery was the whole thing to make it more active, i'm glad you noticed it, hehe
I had one more i wanted to add, but sadly couldn't! A horseman that would charge until you made any kind of damage to it. Of course, in masse it would be hard to stop, so it would have to be bomb tower to dehorse, and then death glare tower to kill the dehorsed soldier. Fun idea!
and OH MAN. That's actually a fantastic idea. Gotta add more of those when the jam ends!!
thanks again for the review!!
