This what im currently working on. Not gonna go on to competition, but whatsoever.
Balloon Dodge
Fretta gamemode with big vertical map, where theres spawning a lot of ballons on the ground and you try to dodge them. The winner is who is the last man standing. It will be quick rounds and very funny to noobs. The balloons are also specified with colors so they do different amount of damage. Players got 250 health.
Balloons:
Green – The weakest balloon, it will only cause 10 damage, and it will be spawned a lot in a round.
Blue – Its a bit harder than green balloon, it will cause 25 damage per hit, and there will be generally much of them.
Yellow – Its much harder than blue, it will cause 50 damage on hit, and there will be like 30 of them per round.
Orange – Its a strong one, causing 100 damage! There will be like 15 of them per round.
Red-You don't wanna meet this one, it will cause 210 damage, so you must be carefully with these. Only 5 of them are seen in game.
Spy-It will change colors between the ones that have been descripted before. If it hits you, you will die instantly exploding and it will cause much damage to near players. There will be only 1-2 per round.
Powerups:
Shield-It will protect you from certain damage.
Perhaps weapons for shooting others?
Any ideas are appericiated, fuck i can't spell it.

This is still in process. And needs ideas/fixing.
EDIT*
