My kids are like 7 & 9 years old, and I want to expand their horizons away from the PS4 and into indie PC games. Im working into creating games with them, and I want to start that out by letting them play some first to get them excited. Specifically, I need games that are kid appropriate, simple-ish controls (point and click, or RPG maker-like controls), cute art. Cats are a bonus?

How about an RPG Maker game about a cat that goes adventuring and makes silly animal friends along the way?

I just finished a demo for my game! Very simple controls and some cute visuals https://smellfet123.itch.io/slime

All my games are child-friendly.

This one is easy to play:  https://evolutionarygames.itch.io/cloud-calming

This one has a free demo and has cute cartoons https://evolutionarygames.itch.io/pizzantropia

My girls are 7 and 4 and are fans of my games (which is nice! :-D) - though they more often watch than play themselves.  Some of my games are vey simple (because of my limited coding skills at the time) and / or child-friendly because made them for my kids initially.
