Train Goes Right, I think it was called, is a relaxing physics-based isometric view, Sega Saturn/PS1-styled game where you build a railroad by hand.

You lay the ties, put the ballast down, place the rails down, and hammer everything in. Then you can hop in a handcart and ride your track you built. The trailer implies the full game will have actual train locomotives and stuff too. It’s very chill and a fun game to play in small spurts of time. You can save your progress and come back at any time so there is no sort of looming Majora’s Mask moon.
