thoosie - Draw & Ride Coasters

thoosie is a 2D roller coaster creation simulator! Draw coasters freehand, straight lines, or arcs. Add brake runs, barrel rolls/turnarounds, loops, and launches. You can also create “trigger” tracks - when the train crosses a section of track, other tracks are affected. While the game has obvious limitations, there’s no shortage of designs to try and experiments to run!

Create your track and save it as a json, and load in any track design you please. You can also post your coaster to the gallery - no accounts or auth, so your posts are anonymous.

The game engine does something really, really unique. wink There are no graphics, it’s procedurally generated code. Music, however, was provided by some buddies who are good at that type of thing. It started with claude chat, but for a variety of reasons I decided to get the thing set up in a github repo and start working via claude code instead. It was just a lot of play testing and bug testing, which felt like it would never end.
