v0.4.0-alpha

Further improve performance for the demanding algorithms. Now the playfield is cleared after line completes in almost real time (a couple frames). To make this much better is a tough problem, probably will need a lot of hand-written asm.

The game is mechanically the same as v0.3.5-alpha.

v0.3.5-alpha

Functionally the same as v0.3.0-alpha but includes performance improvements making the game feel snappier.

v0.3.0-alpha

Game is pretty much functionally complete. It is optimized to the point where it's playable. There is score-keeping, lives counting, game over and continue mechanics, etc. The graphics are a bit better, still should be improved but workable. Most of the placeholder development features are removed. The font is finalized.

v0.2.0-alpha

The game has been partially optimized, has better graphics, and some sound effects.

Build for counting 4-connected islands

Instead of playing JezzBall, this build provides a solution for finding the count of 4-connected islands in the playfield.

Each playfield byte can initially be 0 (WATER) or 1 (LAND). Water tiles are drawn using the background tile instead of a numeric zero for clarity.

The game launches directly to the playfield and doesn't contain balls or player sprites. Press A to solve the playfield.

CLEAR% in the HUD will display the count of islands found.

Each discovered island will be marked with a unique number (>1).

This works by walking over every playfield tile, skipping water tiles and already-discovered land tiles, and upon finding an undiscovered land tile, walking the entire island connected to that origin land tile and marking the island by setting the tiles comprising it with a unique number (>1).

First release

The game mechanics are implemented and the game is playable but it needs quite a bit of tuning, graphics and colors are early, there is no sound, etc.
