Smeaton's Tower of Greed

Smeaton's Tower Of Greed is a multiplayer arcade game in which players must climb Smeaton's Tower, helping eachother to collect as much treasure as possible, whilst also in direct competition.

Along the way players are faced with the decision; "friendship, or greed?" in circumstances such as reviving your friend... at a cost of half your score, or only the highest-scoring player being allowed to submit their score to the leaderboards.

In-game characters share their energy with physical players through motion detection, so if you want to be greedy and gain treasure in-game, you should probably preserve your physical real-world energy.
