Just like how Portal is an awesome game on controlling and folding space, I want to do something on controlling time. Here's my attempt from LD47. Would love to hear your feedback so I can try to tweak the design and find better mechanics. OR if you know of similar games / have your ideas, tell me so I can try them :)

Problems I ran into with making the mechanics:
* What does it mean to fold/manipulate time? I thought of Portal's "bring a different space from the current time to me", and I swapped time and space,  so I got "bring a different time from the current space to me". 
* What game genres work here? Action? Puzzle? RPG? FPS? Puzzle seemed like the obvious choice since Portal was my inspiration.
* How to decide which time to bring back? In Portal  you point. In this game of mine you hit "Record"?
* How to decide how to play that time back? I had what you "Recorded" looping, to match the theme of Ludum Dare (Stuck in a Loop).
* Altering the past did not feel right because it already happened, so some of the mechanics can feel a bit inconsistent to avoid that. For example, if you collide with your past self, it should be able to affect you, but no the other way around. However the physical question remains: If past self is exerting some force on future self, should past self feel the opposite force?

Again, would love to hear your theories on how to solve these while not causing any logical paradoxes :D
