I like sokoban style games and I did enjoy this but MAN is it unforgiving lol. I'm not sure if there's leeway for winning or if I just happened to complete the first 2 levels with the exact number of moves haha. I feel as though you could have done with another level of pushing the box to the correct location with the bomb before introducing ice mechanics too.
The art and narrative are really good though, with the cartoony scientists and assistant having to solve the bomb threat. The drawings are cute and I liked the lil RC car. I think you've done a good job with this, just might need some tweaking on the bomb numbers.
