Hey, like the idea! I did find it too difficult (couldn't make it past wave 1 haha) but good work! Maybe a bigger arena would help, where I'd have more time to swap between placing units and controlling them.
Thanks for giving my game a try and for the input! Make sure you're using your right click abilities. Otherwise, I hear you: it seems like I may have gotten too used to playing the game when I was tuning difficulty 😆
