Interesting artstyle and fun premise. I had no trouble with the balance on the game, I think I encountered the proper combination of mobs and upgrades early on and it felt good to get powerful early. I accidentally left the dungeon early and only rescued half the cats, but I guess I should've seen it coming that the door leading to the OUTSIDE of the map would take me out, haha.
Overall, I really enjoyed this entry and I'll probably go back to make a max cats run once I play and rate more games. Clearly above average entry!
