Ciao. I just released on Itch.io my first Playdate game. It's a roguelike-flavored, single-player shifting-maze card game for Playdate, where you're the Minotaur trying to get out of your own labyrinth.
You can download it from free from here: Minotauros
I wrote it in Lua. Instead of using png, all the graphics and animations in the game has been done by using Playdate SDK graphics primitive, dither patterns, and perlin noise function.
The music instead is coming from Ovani; Humble Bundles are great for getting game assets 
The game is built as a love letter to board games like Ravensburger Labyrinth and Matagot Room 25.
Lastly, the game is supposed to be in version 1.0, but I do not exclude to make updates. Thus feel free to reach out to me for any feedback, suggestion, or question.
Thanks
