So far this is my project of Dragonscape (based on Project boost). It so far has 5 playable levels. I could not make it into a build because of unknown errors, so I decided to finish the game completely first, then export dependencies from all completed levels/scenes, put them in a new project, then make a build hoping the errors will not follow the exported assets.
The early version of this game demonstrates you escaping as Dragon soul through the traps and obstacles in the underworld.
