Here are some ideas for the game!
Also, celebration for Smash Bros for 3DS coming out in the US today!
Lets put the cape item into the game everyone!
+The ability to fly for a few seconds
+Any aerial attacks while the item is active does 3+ more damage
-Any regular ground attacks (not special attacks) while the item is active is -3 less damage (minimum:1)
The item lasts for 20 seconds to put in full potential
Certain characters should have a double jump.
To be honest thats all my ideas, but hopefully they get into the game!
