Cat Heroes - Merge Defense

I love this game. I remember playing it lockdown. The music perfectly captures the vibe of cats defending from evil balls(?) in space. One thing I would love is if there was an enemy guide because I can't remember what each enemy type does (as a boss). Would give 10 stars if I could.

I've gotten past level 1000 finally, I have been disappointed in the past with the game restarting my progress if I close it too quickly after upgrading, but other than that it has been such a fun tower defense game. You don't need wifi, and ads are completely optional to play, but I choose to get prizes through ads. I get bored of games often but this one I am always returning to.

Fun, interactive game that's just challenging enough. Thank you! Edit: After playing this game for 9 months, it's such a breath of fresh air. You don't ever HAVE to watch an ad, though doing so doubles your rubies and stars. "Winning" gets you reincarnated, but with all your currency at level of cats. This is the only game I've ever played that I truly enjoy bc it's aesthetically pleasing, no stress, no waiting for your characters to hatch, and the ad options are not annoying. Thank you so much.
