While the project itself is still in development and is very much a 'done when it's done' kind of deal we decided to put together a demo of World 1, and some additional later game levels, just to get some broader feedback and some more eyes on the project.
We have a page on RMN set up for the project, or you can download the demo directly here. (Note it is not Beta 5 compatible, the very first stage softlocks due to a B5 change to clearpipes)
Update February 21st 2021: Fixed the Star Coin index for Fat Tum Forest.
