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.

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.

Simplify the handling of the dirty tiles to just store the dirty word and not keep the array of dirty tile offsets. Have the flea use game and non-game dirty tiles to fix the problem with LHS tiles being marked dirty all the time.

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.

Provide an API to set the default speed of a flea or a scorpion. This will allow the speed to be changed for different levels in the game. Need to add this API for spiders also.
