This is a digging mini-game for 2 players. It cannot be played single. Dig you way through the ground collecting bubbles and trying to reach the goal first. Trigger traps for your rival and if you’re behind, the bonus room might turn the match around in your favor again. 
The video included is from an old version though. The current one does look quite alot better.
Version 1.5 is having a major bug that I just found. :(
I’m locking the level until it’s repaired tomorrow.
The game is back up! Everything is fixed now.
Great idea for a level!
it’s like a 3 dimensional arcade game 5/5 for being original
