This is such a crazy creative take for the jam's theme!
The way it works gameplay wise is technically simple, but the cleverness of having the shadow projection of the towers be the ones to actually shoot the enemies is superb!
Having the orb not be able to coexist in the same place as a tower was also an interesting move, as it means you have to always take in consideration if that position you're giving to a tower won't possibly get you in a tricky situation later down in line.
Having part of the music's instruments only show up when an enemy's near a heart was an awesome touch!
I can definitely see some really fun ideas coming out of this one. It can go to so many directions!
The cleverness opened my mind to new possibilites. Awesome game!
