weather

[robust latch]

Rain or wind during matches can affect the ball's performance during the game.

[warm vapor]

I think the idea sounds cool at first. But it wouldn’t really make sense. Because we play in an enclosed box with a controlled environment. I assume it will always be dry, and the wind levels (air conditioning) will be consistent for every match

It would be fun as a casual mode(like 4v4 fireball), like if after each goal the environment changes to something else(like strong wind, frozen ground, random earthquakes etc.)

I agree, limited time game modes can be a good way to keep players engaged.

Besides your examples I'd love a low gravity game mode (for the ball only), or a game mode where the ball has more velocity from shots and passes
