There are some points i'll try to address as soon as possible : 

1. Add the opportunity to set the game's time ( Added a time selector when everyone is ready ! 15 seconds incremental) 
2. Reduce the characters floatiness ( Changed the gravity effect on characters so it is more ''crispy'' )
3. Add the game starting animation for games with 3 and 4 players. (Added provisory animations for 2 - 3 - 4 players !)
4.  Keep players from selecting the same characters.  ( Players can't pick the same character now, cased too much confusion with colors )
5.  Add an endgame animation to show scores. ( End game animation added to show score ) * visuals temporary !
6.  Add some dynamic items / props in the maps.
7. Add Sound as soon as i have some.
8. Make better menus
9. New projectile ability to target less reachable platforms( maybe with bullet drop )

As soon as these points are done, i'll put out a new list

Thanks :D
