This is a series of "sliding blocks" puzzles.

I (re)discover this kind of puzzles when viewing https://www.youtube.com/watch?v=RFLt8daBbUo

Later, I found more puzzles at https://www.cimt.org.uk/resources/puzzles/slideblk/epuzzle.htm

and on other sites too.

I hope you enjoy it :)

I am open to collaboration. I will handle the programming and need a creative partner to contribute with game concepts, design, and animations.
