Game Idea #2: Rooftop Escape (Patreon)

Rooftop Escape (working title) is a 3D, first-person platformer. You play as a normal-sized individual whose sole goal is to escape from a skyscraper-sized giantess whilst parkouring across the city rooftops. Think Mirror's Edge but with a very big woman hunting you down.

As far as movement goes, the player(s) will flow around obstacles using parkour, use cranes and wires to get from building to building, and potentially have unlockable gadgets to aid them in their futile run from destruction. Did someone say grappling hooks?

While movement is important, building destruction will be the star of the show here. I've done a lot of research into how buildings collapse and break apart, and I'd like to make it semi-realistic. It'll involve lots of smoke. This will also provide an ever-changing environment for the player(s) to work with.

Multiplayer would fit very well in this game; multiple tinies try to escape a player-controlled giantess, scattering about and trying their best to survive. Meanwhile, the giantess will be working to trap and kill tinies, one smashed building at a time.

The end goal for the tinies is still up in the air; a time limit would be a bit anticlimactic, but would allow for an infinitely generating city. A finish line could be fun. Perhaps giving the tinies weapons to weaken or even stop the giantess would be a fitting end, but that would create a whole world of balancing problems.

What do you guys think? What should the end goal(s) of the tinies be? What kinds of gadgets could they have to help them maneuver the rooftops? What other features could be added? QUESTIONS!!!
