As a sokoban lover it nice to see another game with those mechanics. The channel digging is in theory a nice layer on top, but the movement kinda makes it more tedious as it should be. By this I mean the ability to not be able just look into a direction without moving.
Explaining a few mechanics would be nice for those who are not into the genre, but is not a dealbreaker imo. Lost to Area 2-s hay bale maze.
Kinda a bummer that the game lacks sfx and msx, it would have been lifted so much by those. Otherwise a pretty cool game you can follow up on to make a full release!
