I'll kick this board off so people can see how things should be submitted here.
Name: Cannon Fodder
Location: Wherever the circus is
Description: Very similar to the bombchu bowling alley in OoT. The player launches a projectile to a target through a series of moving obstacles. The farther the projectile gets, the bigger the prize! Hit the bulls-eye of the target for a grand prize. What's the projectile you ask? The player itself

Obstacles include moving walls, giant spike traps, flying explosives, a giant cuu cuu, fireballs, and --- Noko the Immovable. Certain obstacles will slow down the player, while others will just outright stop the player. Obstacle combinations are generated randomly and increase in numbers as the player gets farther. The player will also be able to steer left and right while airborn (yes I know this makes NO sense). Starting from rest, the player has about 1.5 times the needed speed to reach the bullseye and decelerates slowly.
wood walls: -12.5% speed,
stone walls: complete stop
spike traps: -90% speed
Bombs: +10% speed, -10% speed if player is on fire
giant cuu cuu: -30% speed
fireballs: -5% speed and lights player on fire for 5 seconds. Time stacks if more than one is hit (i.e. if there are 3 seconds left and another is hit, there are now 8 seconds left)
waterfall: -5% speed, extinguishes fire
Noko: -110% speed (i.e. you get knocked back), will only appear once throughout the course
prizes:
< 30m: 10 rupees
30 - 40m: 20 rupees
41 - 50m: 50 rupees
51m - 100m(end): Bomb bag upgrade
101m(must hit bullseye): heart piece
