Basically Hide & Seek, but as a One Button Game.
With a single button per player, it’s hard to move around. That’s why, on purpose, the movement (of hiders) is pretty much silly and random. Just press your button and … see where you end up. This makes hiding actually quite difficult, no matter what the arenas look like, no matter how much time the hiders get.
I envisioned the look and movement a bit like how in LEGO Voyagers your single-block characters roll and stick to stuff.
