Did you play an old Genesis game called "Subterrania"? This game totally reminded me of that, you may want to check it out if you don't know it (I found a youtube video for you in this link, and I promise it's not Rick Astley).
This is fun, I hope you continue with it and develop some more levels. I liked the music, the sound effects, the particles, it's just too short :D.
Also, you made the explosion sound with your mouth, right? :D It's awesome!
