I've recently had an idea to introduce time travel into games, it's still only in the developing stages atm

this first one needs a lot of work (I'm going to revamp it soon with new sections/subsections, restructure it, and add summaries to make it easy to understand)
let me know what you think

Time Portal Chess
this one is complete (I think!) it's a variariation of Snakes and Ladders (I've added some combinations aswell)
