The sounding of explosions were very satisfying and a good match for the "DUH"s I was expressing when I did a bad move.

I liked the concept and linking the theme with a puzzle game. And I like that you found yourself a good start of a core mechanic to expand upon, it required some thought and the mechanic didn't leave me with brute forcing as the best strategy. I could easily see other "isotopes" which would be unstable under different conditions. Of course time is not your friend here and it takes time and lots of play testing to get puzzle games going further. I hope you expand on it :)

I was not good at solving the puzzles, but the concept and execution are really nice.

Fun twist on the sokoban genre! The puzzles just hard enough and I loved that you could just rollback one turn it makes them much more enjoyable.

Very cool, is started to explode a lot on the second level :D!

Nice idea, couldnt get very far as I found the puzzles to be quite challenging!

Like the twist on sokoban paired with the theme!

fun! I find it kind of funny how in vanilla sokoban 2x2 boxes are generally bad... but here they straight-up kill you haha

The mechanic seems like it has some good potential, and its conceptually obvious/simple in some sense, which is very nice. I think my favorite was level 3; it took a surprising number of steps!
