I have a few question to ask about Melee

Can the melee have multi modes?
For example:
- can put on back
- shield mode (25% dmg absorbed)
- can change it appearance
- heal (1hp/second)
- show off

Can the melee have slash attack?

Also, when will the submissions be picked and will the participants get notifications in-game or e-mail if their submissions get picked or rejected?
