In my limited experience, I never played a Sokoban where boxes could explode. I am also impressed by the fact that it is done in JS. Well done! :)
The style was coherent and understandable, the mechanic was not too complicated, and I understood hat was needed to do! Sweet and highly addictive with nice level design! Bigger rooms made me think twice, usually sokoban are simple, and this challenge made it way more engaging for me.
