Here are my ideas :
-Rocket PowerUp! (like the Mariokart rocket, it will increase marble's speed for long time than the SuperSpeed!)
-Rotating platforms!
-Zigzag floor! (when the marble enters this zone, marble won't stop zig-zagging!)
-Detonator! (a mini hidden bomb which will make all the mines explode on a specified zone)
-Virus Powerup! (infect the bumpers)
-Slingshots and catapults
-Animated caution signs
-Silly floor (worst than the random floor, it changes the marble's direction anytime it stays on!)
-Bomb floor! (it will have the WTF Boom sound. If the marble stays too long on that floor, 5, 4, 3, 2, 1, WTF BOOM!!!! the marble gets blown away! 50x powerful than the nuke!)
-Antiwind Powerup! (when activated, tornadoes and duct fans don't have any effect on the marble!)
That's all I've got for now.
You forget a thousand things everyday. Make sure Marble Blast isn't one of 'em.
