Matthew Umana (username: Crimzen): My role is scripter and level designer. I have done the interactions of the player with the environment (trees, ice, water). I have utilized Tony's Day/Night cycle script to affect what event occur at a given point in the day. In addition to that, when the player presses "t", the time of day will accelerate.
If you want to get past an ice barrier you must wait until the daytime for it to melt, if you want to get past a tree barrier you must also wait until the day for the tree to grow, and finally, if you want the water to freeze you must wait until the night for it to do so.
The time it take for an entire day to pass is 6 minutes but every time the player presses "t" this time shortens (hints the time traveling aspect).
