What a beautiful game with such a clever mechanic. The challenge of managing your the tiles below grows much more challenging as the enemies become more diverse and plentiful. The damage dropping into the grid below is so clever, it adds an additional layer of positional puzzling when the screen fills with enemies. I only got to use a couple perks, but I can see they add a lot to the mix. I am astounded by the 200+ high scores. I was playing on desktop but this would be great on mobile, this is right up my alley for puzzling/quick session phone games.
