At our November Mini Game Jam I teamed up with artist Alfonso Montón, forging an epic prototype for the theme “time” (and possibly “trap”):
Don’t be fooled by their cute appearance! If you hesitate one moment, a Time Crab will envelop you in a Time Bubble and begin to tear you to shreds with its Time Claws*!
Fortunately you are a Time Crab. So is your opponent! May the fight begin!
….work like a local field of bullet time: It slows everything inside down, but you a fair bit less than everything else. You can use it in two ways: Aggressive, by throwing it at an enemy and proceeding to shoot at him while moves slooowly, or defensive to dodge bullets. The shooting mechanic makes the prototype not very playable, but I really like the bubbles – in fact I might use them in another game. (And yeah, they are like a more selective time slow ring in world 6 of Braid. I totally forgot that it even existed!)
And a Dropped Idea
I quite liked my second idea too, but there was hardly enough time for it: A cross between Tower Defense and Capture The Flag. First you set up your base with turrets and traps, and then you leave to get the enemys flag. You can detect and disarm traps, but only while you aren’t carrying the flag – so prepare a safe way out. PvP would probably be enabled (and might include Time Bubbles) and minions.
Okay, now that I think about it, it sounds a bit like a more RTS-like DotA.
*) Time Claws are not included in the prototype and will later be added as a purchasable expansion pack.
