I played this game on my stream (VOD).
Overall, this game was fun! I'm a fan of clicker games, and had lots of fun clicking the cats. I played until I ran out of upgrades to buy :)
I really liked the sniper cat, since it could earn cash even if I didn't click. I also enjoyed the explosive cats; it was fun watching it do AOE damage to the other cats in the vicinity.
I found it a little difficult to click on the cats sometimes, and my hand got pretty tired after a while. It might be a good game for mobile, since it might be easy to press on the screen than move the mouse around.
I noticed that the purchase screen was to the right of the main game screen, which caused some cats to appear there. I don't know if it was intentional or a bug, but it was kind of fun to click on the cats that appeared there too.
The little easter eggs like clicking on the sunglasses of the merchant was a nice touch!
