Hello!
We are currently finishing up a sequel to Spacebar called Spacebar X, set to release this month!
The main differences are that jump is now combined with flip and fly, offering unique patterns that can make use of the combined mechanics. There will also be a new warp mechanic that allows you to teleport to an indicator on the screen.
If you enjoyed Spacebar, be sure to wishlist Spacebar X so you will be notified of the release!
