I believe I have fixed the invisible mushroom bug. I have inspected all of the code which sets a tileType to something that didn't mark the tile as dirty. I believe the problem occurred because the code in update which placed/changed mushrooms assumed that the draw code which then mark the tile as dirty because the bug which caused the change which dirty that tile. But that is an assumption. If the bug is shot, perhaps the draw routine will not mark the tile dirty. So, now the tile is always marked dirty right at the point where the mushroom is placed. I believe this will fix the problem but more play testing is required to confirm I don't see it anymore.

Implement stereo sound. Sounds now come from the left or the right speaker depending on where the sound is coming from on the screen as much as possible.

Disassociate sound resources from the generators they are connected with. Use multiple generators to play multiple shot sounds at the same time. It sounds weird but it kind of works.

Add sounds for shooting, killing bugs, dying and resetting mushrooms after death. The shoot sound isn't great because it doesn't restart when rapid fire is happening but this is a start.

Change the spider score colour to be the same as mushroom colours so the player does not detect it as a collision. Add code to display the number of lives and add to the number of lives ever 12,000 points. This lays the groundwork for handling player death and collisions.

Replace the C code which built tables at game launch time with a script which generates these tables at build time. This reduces the start time of the application and saves code space and is a necessary step before adding some new tables to handle the mouse efficiently.

Add the code to handle restricting the spider to lower and lower rows as the score goes up. This is the final bit of game logic necessary for the bugs in the game I think.

Implement the code to add the flea at the right time. This includes tracking the score in multiples of 20,000 and adjusting the number of mushrooms required in the infield before a flea will appear. Simplify the other score based thresholds which are based on multiples of 20,000 to use this test. Add debug which allows me to add 20,000 to the score whenever I want so I can test these thresholds more easily.

Change the code for centipede speed to skip slow speed segments entirely once the score is more than 40000.
...
Add segments at the start of the next level in reverse order so the single head segments are added first. This ensures they do collision detection properly in the updateSegment code.
Fix a bug where a set of 16 tiles were always marked as occupied by a centipede segment because we didn't clear it properly on each updateSegment call. This fixed a problem with segments changing direction for no apparent reason.
Test for collisions on the two tiles the segment is spanning and change direction if either is occupied. This should eliminate single segments travelling on top of each other.
Add scorpions randomly during a game once we get to level 4. They are added with a 1 in 512 chance every 60 seconds so you should see a scorpion about once every 10 seconds or so.
When the score is above 20000, add scorpions at fast speed 3/4 of the time, slow speed the other 1/4 of the time. Lower scores, the scorpion is always slow.

Implement the code to add spiders to the game. From my testing, it looks like 2 seconds after a spider leaves the game (either shot or off the screen), another one is added. Also, once the score is about 5000, the spiders added will be fast. The only spider behaviour I know of which is so far not implemented is as the player reaches higher levels, the spider constrains itself closer and closer to the bottom of the screen.

Hook up the score. Shooting fleas, spiders, scorpions or segments will increase the score. We track the score in two ways. One is just as a 32-bit unsigned integer for doing numeric comparisons on the score (say to the high score list to be implemented in the future) and secondly as a series of numeric digits displayed in a tile. Both are updated.

Change from an array of structs to a series of individual arrays for the tile information. This makes it easier to index into the arrays because the tile number * 2 is the offset, rather than tile number * 16.
