Playdate/PC: Download from Github. Use Playdate Simulator to run on PC.
Web: generated with pdlove (likely a bit buggy).
I had a strange mood and implemented the complete set of base mechanics for Void Stranger for Playdate. I also redrew the graphics from scratch for 1-bit. No generative AI was used (though the web demo was generated with pdlove, a tool which was built with generative AI).
This is not really a proper game, but it has a few dozen levels so you're welcome to play it. I would suggest playing the original game first of course, as there are spoilers for game mechanics in the original within. If you stop playing on level B025 you will most likely avoid the biggest spoilers, though it's conceivably you could discover some of the more deeply hidden mechanics before then. You should also assume there will be unmarked spoilers throughout the remainder of this thread.
Please let me know if you'd like to contribute some additional levels. Maybe this can be fleshed out into a proper game?
