It looks nice and I'm a big fan of Pico-8. Cool concept and the game was really challenging. The only thing I didn't like was that reading and understanding the instruction took long time and it's not really 20s if you have to take your time reading the instructions. The screen is dense of information and that was a bit overwelming. Probably not the best fit for this jam, but overall a fun game.

It looks soo cool.

But i need some time to get that concept around my head :D 
Maybe because i am not that kind of a Chess-Player

It looks very polished and the presentation is great I was confused at start but got the hang of it quickly, my largest strak was 6, good job.

I really like how you cleaned down the classic chess puzzle game, with your own piece spins on top of that! Graphipcs are nice, rules are mostly clear, well done!

One thing: I would love to swap the menu confirm button from O to X so you don’t accidentaly go to the next stage when you want to re-try and have the habit of using O cuz you capture with that!
