Played the first five levels on mobile.
Nice visuals, but very easy in mobile to accidentally input diagonals, undo much needed.
Hoping later levels require you to use your limited pulls, might make for interesting challenges.

Remark : undo is not hard to implement on sokoban.
Instead of saving the board states, a stack of moves with distinction between moves and pushes is enough.

I wondered why I wasnt able to pull. Took me a while to figure out that pulling is limited by hearts. But great game so far :-)

I always wonder how people make these sliding tile puzzles just tricky enough to make you scratch your head, but not so much as to throw a contoller.. you managed to pull it off. Great game.
