The artwork for this game is great and the gameplay is enjoyable! I had trouble figuring out why I needed to clean. After my last cat wouldn't wake up for a long time I went around the house again to see if there was anything else to clean. I found the piece of trash hidden behind the bed, which I now see is in one of your screenshots. After I cleaned it I went back and my cat was awake, so I think the cats waking up is related to the amount you have cleaned? That could use some clarification because I originally thought the cats were on timers or something.
Aside from that little bit of confusion this was a super fun game! I loved collecting an army of cats and jumping around to watch them fly. Thanks for making this!
