You are the blocky character near the bottom.
Hold Z or X to charge a personal bubble for a Left or Right Jump Burst. Charging longer will launch your character farther.

You can charge both directions once on the ground and once in the air.

Attempt to knock the Score Bubbles into eachother to make them combine into larger ones. Once they are sufficiently large, knock them to the bottom of the screen to 'cash it out' for points. This will spawn an additional set of bubbles which you can use to repeat the process.

There's no time limit or failure condition (due to time constraints, funnily enough.)

Known Bugs: Game immediately stops once two bubbles collide.

Omitted Features: Player's jump-bubbles are never drawn, and only indicated as text. Player does not attach to bubbles it touches. No sound or particle effects.

Change Log: Game no longer crashes when the bubbles merge. Changed the first screenshot to the third screenshot taken. Added third screenshot.
