Project Moment is my current game project that revolves around time. (Haven't thought of a good title yet.)
As someone given a limited power to manipulate time, you journey through many foreign lands, meet interesting new people, and create and use weapon mods.
Battles are unique - each turn you are given a short amount of seconds to act however you like: attack, heal, set up traps or blockades, etc. Time is also your health - the less you get hit, the longer you can act. Enemies will generally have less time to act, but the same concept applies.
Weapon mods are made of materials or elements. For example, two ice elements will create a Freeze mod that does 10 damage and requires little time to charge.
Mods may also be combined to create new ones. Three Freeze mods will make Triple Freeze, each shard dealing 15 damage. In the real scheme of things, combined mods won't be this blunt - but you get the idea.
