I also started another one. This one takes "pick a power disk" to the player's perspective. You choose your own power disks to help you in a series of trials. It also contains a "Menu" In which you select to play "Story Mode" or "Multiplayer".
It's going to be fun specially for multiplayer! It's also made with several disk skydomes so it will qualify.
ps: It's GLOBNAR from Gravity Falls.
I'm so excited to finish this project!
