Hello! I really nice the graphics for this game! It was made with GB Studio? :)
I was trying to play with the Firefox browser and I couldn’t hear the song, so I downloaded the game and everything sounded right :D (I love that song too).
I went through some puzzles and my character disappeared here and the game crashed. I’m sending you the image with the placement of the rocks and the movement I’ve done so maybe you can reproduce it.
Aside from that, very good looking game! A bit challenging for me as I’m not very good at Sokoban games. :p
