Sorry to say but this sucks majorly.
I think its a really cool premise that has a lot of potential, but the way its executed just doesn't work very well whatsoever.
Before that though, I will say I do enjoy the game aethstetically quite a lot. 2D characters in 3D worlds is a kind of look that I really enjoy and I think this games does it well enough. Even though it is very basic, I do like how the music changes to match the timezone as well.
Alright, now for everything else
The controls completely suck: The movement is too slippery, the jumping is stiff and inconsistent, and the physics in general are terrible. Things like walking up slopes or bouncing off of enemies causes all sorts of problems. Not to mention moving platforms, where unless you land perfectly still ontop of them you will slide off the edge immediately upon landing. I also encountered a weird problem where the character would continue moving whenever I would change timeperiods.
Speaking of, the timechanging gimmick is uninteresting and boring. What most obstacles boil down to is "Wait for the game to tell you to change timezones and then change to whatever one open the path forward". Theres no interesting clues to indicate what timezone you need to jump to, there's no freedom to do so whenever you want to(essentially turning the whole thing into an elaborate key), theres no punishment in guessing wrong, theres nothing. And the same thing applies to the rotation "mechanic"; You wait for the game to tell you to use it and then...you do. The only ways I can think of salvaging it would be by A. Letting the player change time periods whenever they want B. when they enter the menu to do so, pause the game entirely and unpause when the player switches timezones and C. show the time change in real time so the player can judge whether they're making the right decision or not. As for the rotation "mechanic" I'd honestly say to either get rid of it or turn it into a powerup or something. As it is right now it completely stops the game in its tracks for what is, yet again, essentially an elaborate key.
This game HAS potential, but in its current form it feels less like a loving indie gameand more like shovelware
