The game dont have too much to do. Just travel through ages and wait the finish line appear. As this is just a rough concept you may improve later, for now is a good idea making this game more playable, like, if its an exploration game let players explore, not wait for time warpers to click buttons. There should have some way players can notice if they are getting closer or not to the finish line, i passed even more than 5m waiting it appear and nothing lol. There could have more race elements here too. At least it follows the theme well :)

Thank you for trying the game. Appreciate the suggestions. My initial idea for this was a Mario Kart-style racing game where there were advantages to switching timelines, I'm still trying to figure out how to make that work as I'm not sure if it should be like a power-up or just a portal you drive into. The lack of racing elements is also the fact that I don't know how to do the AI yet for it. However, if I made the level design easier, having only a few possible switching points, that would also simplify designing the AI "brain" to compete with the player. I like your exploration idea though too. Maybe a race to collect items scattered in different timelines and see how quick you can complete it by jumping around and using the various road networks that exist in different times.
