Last night we created a new and improved version of “Hanging off a Bar” in a 1-night hackathon. The goal of the game is to “hang on” as long as you can, not letting go and falling into the virtual river below you. There are some rafts coming by from time to time, on which you can jump to rest, but you have to be quick, as they keep moving and you have to jump back up onto the bar. Winner is who can hang on the longest. We will show this game at the Open Day and use it afterwards to explore the relationship between exertion investment and particular game elements.
