Really impressive entry! The tutorial explains the mechanic very good!
The game becomes pretty thrilling once everything starts exploding. I made it to the exit by mere milliseconds several times, which felt incredibly satisfying!
Also, cutscenes and an actual story in a jam game, especially when they are not even the main focus? Serious dedication! The music is great too and fits the whole experience really well.
My only small thought was whether a preview of each bombs blast area during the planning phase might be helpful. On the other hand, that might take away some of the tension and experimentation, so I am not even sure :D
Very polished and fun game!
