Thank you for the kind words! It's definitely a bit on the harder side, even I can't always win levels (depending on RNG). Balancing was something I just had to give up in favor of polish near the end. Glad you enjoyed it!
I can't take credit for that level of creativity though, there's at least 2 more tower defense games in the jam (check the comments on this page for them). We all found each other somehow :D
