Libre Memory Game

This is a Free/Libre and Open Source memory game made with Godot.
There are multiple card sets and difficulties to play with.
The "Very Hard" difficulty requires you to find 3 cards per image instead of 2.

- New multiplayer hotseat mode (thanks to @kevin_korslund)
- For the mobile version, switch to Godot's "compability" renderer to better support older devices and to avoid some rendering bugs
- Fixed some bugs
