v0.1 is public, which is 2 months old.
v0.2 and v0.2.0.1 are early access as of now. This will shift in the future, but it takes time.
I understand the frustration with the bugs in the early prototype, but as it fulfills its job as a prototype despite the game-breaking bugs, I will focus on continuing development and then replace the free version as new versions come out.
