Sweet. I may as well throw another idea out there; How about a boss with two parts: In the first part, You follow him through a canyon, Un-armed. On either side is forest. You must jump to each platform to keep up with him, but avoid the unstable flashing bricks. The boss will pretty much Jump too. The only rush you'll have is the 30 second delay after the boss reaches the fight door. After 30 seconds, a restart plate should appear above the entry cliff's grass plate. This starts the chase over again. The door will close whether the 30-delay ends or a bit after you enter.
PART 2: The boss will proceed to fire spears at you from an unreachable "donut hole" in the center of the stage. This is where you get your weapon, *insert one-time throw weapon here* from a barrel. You have to guide the boss within firing range of any of the barrels, then immediately dodge the spear headed for the barrel. In place of this barrel should be *insert*. You can throw this at the boss. Repeat this until the boss dies, then you have beaten him!
Preferences: Boss attire: Yellow skin, white long sleeve shirt, green pants + shoes. Size: 150%+.
Part 1: Green top, add trees, brown downwards, Green platforms.
Part 2: Same top and bottom for main + low floor, as circular and wide as possible, including the gap!
Sky: Bright or dark blue w/ stars depending.
Music: A good bongo rythm would be nice for part 1, as well as part 2 with an added electric bass/whatever melody.
Damn, I'm late. lol @ using my template quote though.
