Thanks so much for the feedback! It means a lot that you like the graphics and the story; I put a lot of heart into it there, and while I ultimately regret not focusing on the gameplay first, I'm happy with how everything else came out.
I absolutely agree with both of the problems you mentioned. The platforming issues were a problem for me throughout, and I've definitely got to keep working on cleaning them up more. I eventually got them to be functional (the state the game was in when I uploaded it), but to make things more functional and fun, they need to be smoother. I actually did have time coloration planned for the entire screen when a time zone was entered, but I couldn't get it to work well with my trigger set up. In my quick tests, the player would cross one of the barriers and that color would lay over the entire screen at a very low opacity, so you could tell what kind of time you were in. Ultimately it didn't make it in for this deadline, but it's something I really want to work on, or at the very least update so it's more clear to the player.
Thank you so much for taking the time to play it and to leave feedback, it really means a lot! I was pretty intimidated when I saw the rest of the games that got submitted, so it's really cool to get to hear what you thought. :D
