A downloadable game for Windows and macOS

Space Rex is an endless runner with dinosaurs (in space!) initially built during a 48-hour game jam. We are releasing the final game jam build (Space Rex 48) as well as an updated polished version, so it's kind of like getting an early access.

We had more features that we wanted to add, but had to cut them to meet time constraints and allow for last minute polishing/fine tuning to make Space Rex even better at the end of the jam.


It's an autorunner, so all you need to do is jump and stay alive while gaining points for distance traveled and enemies defeated.

Press space to start.

Once in the game, press space to jump, and hold it to jump higher.

Holding space can also slow your fall.

Jump on enemies for points, except for the stegosaurus because they're pointy.

That's it.
