About the game

The objective in this game is to blow at a bubble to guide it through a house. If the bubble hits any obstacle or wall, the bubble pops and the player loses a life. The player can blow at certain obstacles like candles to put out the flame.
There are other ports for this game, but only very few are TASable and I'm not familiar with the emulators of any of those ports. Also, the graphics distinguish very much from the gameboy port. I grew up with the gameboy port and I prefer this one over any other version there is.

About the run

  • Uses programming errors in the game (small hitbox abuse, animation skip)
  • Genre: Action
Used emulator: VisualBoyAdvance v21-interim
There are two time-saving tricks:
- By pressing the button at a certain frame, the bubble will cover more distance. If you blow at the bubble the frame after this frame, the distance the bubble would cover decreases (it slows it down). The special frame to blow the bubble is about every 18th frame.
- If the ghost faces downward at the time the bubble hits the end of a room, most of his victory animation will be skipped, saving time.

Level-specific

Hall 9: The upper route is impossible.
Hall 13: I could have blown at the elephant for points, but it adds 2 lag frames so I didn't.

Possible improvements?

The only theory for an improvement I could think of is to alternate between diagonal and horizontal (or vertical) movement because the special frames seem to be different for either of these directions. Instead of getting the special frame every 16th frame, it might be possible to get it every 8th frame while alternating between directions. I didn't test this idea.

Closing words

Enjoy the run.

FractalFusion: Judging.
FractalFusion: Good viewer response, and the author keeps it interesting by staying as close to obstacles as possible. Accepting for publication.
