The layout and assets usage was good. Although I think the game gets stale after a while, you have ONE tower and you have to move it around for upgrades, I think maybe picking up the upgrades and taking them to the tower or even unlocking new towers could make the game more interesting. You can also defo add a randomizer to these characters to have more HP, be faster, take more water, even if just visually colored to tell the difference it’d be huge for entertainment and stopping the game from getting stale fast.
Good luck on getting a new mouse and good luck on the jam!
