I was expecting this to be a silly little shitpost of a game, but it's actually surprisingly hard. It took me two goes just to beat the first level and I'm still trying to figure out a strategy to beat the second level. The game just doesn't seem to give you enough money to build up any meaningful defences, and you get overwhelmed without really being able to do anything about it.
I'm still really enjoying it though, so I'm gonna keep trying and hopefully it'll click soon.
