Hi, I just released an updated demo version of ROLLING BALL GAME DX: Director's Cut. I recommend you read the update notes before playing, as that lists everything new as well as known bugs and planned additions. I also recommend you check out the Player Input Information section on the main page if you have not played the game before.
There are some things I wanted to add for this demo that I was not able to so I may release a patch for this. Please feel free to make any suggestions and give feedback.
Thank you for your interest in my game!
