I like the idea of this game, however, I think some aspects can still be improved:
- Make it possible to skip the wait time for a new wave. After I had built some buildings, I was forced to wait, which does not come in favor of players
- I encountered a camera bug: I think a cutscene was meant to play or sth like that, but the camera moved to another seemingly random location.
- I like the minimalistic UI, but a tutorial or some kind of introduction in how to build stuff and control villagers would be nice.
- Consider adding a battle theme and maybe a more relaxed tune when you aren't attacked.
All in all, It's a nice game with great potential. Keep working on it :)
