Zoomaroom

Zoomaroom is a momentum based platformer: jumping and running with the
player character (a monkey) quickly builds up speed and leads to improbably
wide or high jumps as well bouncing from walls and other obstacles. In each
level, the goal is to reach the end by using the described techniques. Often
the protagonist also has to use items, e.g. a grapple hook to swing from he
ceiling or the spider web to cling to walls, in order to proceed. Other
obstacles are environmental hazards, e.g. lava, and enemies. Each contact is
deadly, but the level can be instantly restarted in that case. The secondary
objective is to collect five coins, mostly stashed in hard to get places, to
unlock more rooms and costumes.

The game also features a full level editor and allows custom-built levels to
be shared with other players.
