This was sooo goood!! I love these relaxing games and yours has such a nice vibe. It is such a cool and unique idea for tower defense game. The upgrades are great, I like that you can choose different playstyles. Music is very soothing and pleasant. Did you get inspired by Dorfromantik and Townscaper? I think those games are very similar to this one. You should definitely work more on it, add more enemies maybe, more trees/other stuff, more upgrades etc. This needs to be a full game! Good job! :)
