It's ok, it has nice progression, a cat themed game for those who like them (I like cats, I have cats, but I'm not particularly a fan of those kind of games).
The good: It has cute pixel art and nice sound, the progression is simple, the UI for the most part is pretty comfortable and the idea overall is entertaining for a while.
The "not so good": For me it didn't have something that kept me engaged really, I was waiting for that "wow!" moment but it didn't happen, the prestige is fixed, the progression is too controlled, it didn't really let me make meaningful choices, for instance Prestige Points (PP) are capped per level, you can't just keep playing to get more points and make the run meaningful, after you reach the PP Cap it's pointless to keep playing so you're basically forced to restart. I've unlocked all prestige upgrades and all upgrades from the demo, probably the full game has that "wow" moment I was looking for but I couln't find it in the demo. Also, I wish there was a timer counting the time played.
Overall it's not a bad game, it's a cute nice game and if you're a fan of cat themed games you'll like it.
