Meet ChronoBob. Not your average Joe. An adventurer looking for some very special components in a strange place, trying to help out his friend Jarbrain. No spoilers here. You will have to play the game. LOL
About the game
Manoeuvre Bob around these rotating gears (Bob has magnetic shoes). Make him jump in the right direction to collect all the gems and the gem-producing fireflies in the level, escaping a number of vicious enemies that are chasing you.
