Hi fellow cat game maker! Loved the papercraft aesthetic and how clear everything was even without a tutorial or any text at all. Had a lot of fun with the different towers and being able to reroute the enemies so easily.
Did miss the 1st couple of card acquisitions though, probably because I am blind, but got used to clicking on the right hand of the screen to advance so my eyes were over there after a battle had finished. Maybe force showing them to the player and allowing them to skip from there would help with this a little?
Good luck with the rest of development :)
