It's Wednesday! (Also a patch if you want to play it).
Major changes:
-The smash attack has been partially coded. The Mario-blimp interaction physics are not much more than just functional, however (it shouldn't take too long to get it working well, though they probably won't look anything like they do now).
-Graphics are near 100% complete (only things not implemented are when the boss is shooting bullet bills and some smash-related poses). Just for the record, Dinomar's work on this boss's graphics has been absolutely amazing; thanks again.
-No more infinite 1-up chains from the bullet bill attack.
-Left-most tile now animates properly.
-Many minor other changes (for example, the dash attack can now start from either side of the screen instead of just the left side. Stuff like that).
Bugs I know about (that I can think of off the top of my head...):
-The boss still hugs the side of the screen on occasion.
-Glitchy enemy graphics
-The smash attack occasionally causes the boss to disappear if Mario is launched too high.
-The boss's graphics appear flipped when shooting bullet bills from the right side.
-The arena looks off while the level fade-in effect is animating.
-The background is glitchy.
Next update will probably see the completion of the smash attack. Maybe interaction between the boss and Mario as well.
Also, just as a reminder, if anyone's willing to draw one up, I could still use a background for this stage...
and a foreground...
