Fix the last known bug. The "Game Over" screen is now shown when the first of the two players in a two player game runs out of lives.

Fix a bug where it was possible for the player to collide with an exploding bug and then die. Change explosions so they are drawn using background colours which do not result in player collisions.

Look at two pixels wide when detecting collisions with a shot. I believe this solves the problem of shots passing through a centipede.

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.

When looking for collisions, treat the lowest collision as the one that counts. Before this, if you had two stacked mushrooms, it was possible to shoot through the mushroom below and "hit" the mushroom above. This happened because the first collision found was the one that the game handled. If the shot ended up being draw across both mushrooms, then the upper mushroom would record the collision. Now, the collision we care about most is the lowest one which should ensure that the bottom mushroom records to collision always with stacked mushrooms. This is similar to the "shoot through a partial mushroom" problem but is restricted to just when the mushrooms are stacked.

Fix the bug where the tiles on the RHS may be marked dirty and accumulate garbage if the player dies on the RHS. Add some more debug for the crashing bug I am chasing. It looks like more than 12 segments have been added so I am adding debug to detect when the number of segments exceeds 12.

Fix the bug where the "can shoot" indicator was sometimes not cleaned up. The real problem was that the mouseAddress was incorrect on the first frame of the next life. It still pointed to where the player died.

Fix problem on real HW where the player will start the next level shooting if they died while shooting, regardless of the state of the mouse. It now ignores the first poll of the mouse at the start of a level to avoid stale poll information. Add some debug in the code for jumping to the head and body segment draw routines to confirm that the table offsets are sane. I have seen a crash which indicates that sometimes the offset is incorrect.

Fix a long standing bug I have ignored for too long. When adding centipede segments on the left or right, if there was a mushroom right where the segment was arriving, it would try to change direction even though it was still mostly off-screen. This lead to some very strange segment tracks that should never happen. I have added code to ignore blocking mushrooms and not change direction when the segment is partially off-screen.

Fix a crash that would happen if the last centipede segment collided with the player. Both level and player code was trying to start the next level and the corrupted things badly. Now, the level code is always responsible for starting the next level. The player code only restarts a level when the player dies and doesn't finish the level.
