PIKI BOMB

You are bombs.
PIKI BOMB is a co-op party platformer for 2 to 8 players, online or on the same couch. You play little bombs called Pikis, and you all have a fuse. Each level ends at an exit pipe, and the whole team has to get there without exploding. That's the easy part to explain. In practice you'll spend a lot of time saving each other, and a fair amount of time blowing each other up by accident.

Mind your fuse.
Your fuse does most of the work. You throw it to grab a ledge, swing over a gap, pull a block out of the way, or catch a teammate who's about to fall. But it's still a fuse. Get too close to a flame and it lights, and once it's burning you have a few seconds to put it out before you go off.

Don't blow up your friends.
When a Piki explodes, anyone standing next to them usually goes too, and then the next one, and so on. A lot of levels end this way. Wandering off is not safer either: if someone leaves the screen, the whole team dies. So you have to stay close, but not too close, and that balance is pretty much the whole game.

Reach the exit. Together.
Levels are built as puzzles for a group. Some gaps can't be crossed alone, some blocks need pulling from the right spot, and there are saws, spikes and water to deal with (bombs sink). You figure out the room, agree on a plan, and then someone jumps early. That's fine. You try again.
