Hopefully it's not against the rules, if so, please let me know and I'll remove the post. Anyway:

I made an educational open source game for small kids (2-6 yo) where they can match cute animals (currently sea and dinosaur theme packs).

Features:

• cute pictures
• works on both a phone and a tablet
• multiple theme packs
• fully free, no tracking or anything
• there are multiple flavours, one of which bundles all of the assets and doesn't even have the permission to access the internet <- great if you're extra cautious
• big buttons, no reading necessary, small kids friendly

It can be downloaded both from GitHub and the Play Store.

Let me know what you think!
