Nice. Took me 45 min. Hardest part was figuring out certain mechanics.
That sokoban tag is misdirection. You can do a particular thing, that is not possible in sokoban. ;-)
Impressive! I've always thought of sokoban as block pusher puzzles, so I consider my game a "vertical sokoban" with a bit of physics if that makes sense
Since figuring out the rules is part of the puzzle, I can't talk about it without spoilering... ;-)
