I love this kind of game. Nothing much to say ; I stopped at Wave 22 because I never lost and felt like I will never lose. Balancing is the big problem of stats-based game in game jam, and it's really difficult to get a nice one in only one week.
I'm working on more enemys etc for more balacing but like you said it's not easy to get done in one week and (this sounds like an excuse but it's true) I didn't have that much time to work on the game either. Thank you for your honest feedback though!
