Time ship The Higgs Boson is propelled into the dreaded Sands of Time when the caesium engine’s experimental Sun Drive malfunctions. The fearless crew must navigate the sands of time, an ether lost between time lines where countless dangers threaten their chances of returning home to Kalliope Quindecimillenial Erinome.
Some ideas about the game mechanics.
Flight and avoidance. Addition and subtraction as the underlying mechanic.
Timer: is a candle clock. Ok maybe it’s a subatomic candle.
Buffs egg timers and stop watches. Bric-a-brac floating in the ether. Buffs repair damage.
Power ups are floating magic numbers: (1729, 2,8, 28, 50, 82, 126) the bigger the number the better the power up. Power ups fuel or Timer.
Dangers: Sands of time, time leaches, memories in floating tv sets, time gremlins.
Obsticles pillars of time, anomalies, vortexes.
Game levels various shapes associated with time? Spirals, winding paths.
Objective: Make your way to a portal, or multiple portals. The twist not all portals lead home. You are moving through a labyrinth.
Probably over thought this. But figure it’s better to have too much and trim.
Cheers.
Addendum: Maybe the sands of time is too close to other game titles… probably the first thing I should have looked at… all I was left with was the vortex of disappointment.
