Cool idea with two sizes sokoban. Too bad it's too short.

Very cool idea I Liked moving stuff around and it was cool to grow and do the same puzzle but bigger that one was really clever, to improve it I would add sfx/music as well as being able to hold the movement keys down so I don't have to tap it, also I did get softlocked a few times, you should have a restart button to reset the level you are on as I had to refresh and start again each time it happened, overall fun and good idea! :)

Simple design but also very effective! Only point I have is that controls could be a bit smoother (holding instead of tapping to move,  maybe using tab to switch size). Loved the puzzles you were able to create even with only a few levels, more would be great!
