heres new Ideas
1. new power ups for various maps such as A-corn form super Mario deluxe, penguin suit to slide on ice, and drill power up you can drill players from bellow but you have a cool down for drilling under ground and above ground (5secs) so they cannot cheat
2. every time you win you gain some star coins (mini coins) to buy costumes for your character like from Mario odyssey
3. new maps like: under ground where theres lots of holes but there are no brick blocks above but a solid celling, castle (not fortress) where there is lava and swinging platforms, and under water there are fishys and pipes; and the penguin suit is actually use full for the job for swimming
4. And finally Gamemode capture the flag a game mode feature where 1 player gets to have the flag but there's a twist there move ment is slow and the player with the flag gets to use power ups but the mega mushroom and power star when that player gets it, it immediately puts it into its power up selection or gives it to someone else I don't know its a 50 - 50%
well that's all my ideas to make that game more interesting if you want more ideas just call me.
