All players are in a whirlpool. So you’re automatically rotating around and slowly going towards the center more and more.
If you hold your button, you go AGAINST this direction (“middelpuntvliedende kracht”) and fly outward.
This is a One Button Game. You play with multiple people behind the same screen; each player gets only a single button and nothing more.
I can either add a boundary to bounce you back, or simply say that you kill yourself if you fly off the field.
Now you simply hold a wrestling match. You have to be the last one to die into the center of the vortex, while you try to collect good stuff every time you rotate around.
Maybe it takes “effort” to spin out. You start with a limited supply. There are powerups to get back some effort, but you’ll obviously need to time it well / fight with others to grab it.
Yes, I think it’s simplest if you die by falling into the center vortex. This way it can also happen by bumping into others strategically or bouncing off the side too hard.
