Cool game I think more waves would have been good, the music and style of game is nice! It took me a minute to understand how the cards work, as I was clicking them not dragging them onto the path, but it is super cool once I understood, I think it could be improves with more trap types as as well as more waves, also you should have money in the game to spend on more traps that you can get from killing rats! I feel bad for the rats though :( , good game though!
