I really regret playing this with only 10 minutes to spare. I need to come back and play more!
Seriously, very polished, clean interfaces, awesome character designs. The only thing that stood out to me immediately was the soundtrack. It would have been nice to have 2 tracks to jump back and forth between. A preparation-stage song and an intense incoming-wave song. Otherwise, very solid game! I'm coming back to play more as soon as I can!
