I think this is the second time I see that misleading timeline here
I understand it can be frustrating, but 0.5.0 was an early/leaked version, and I have released 0.5.2, which added significant content, including CGs and animations.
Regardless, I'm working to deliver the new update but it'll be done when it's done. I provided more information on the dev diary for those interested in that.
It's been 3 months now since 0.5.2 and it's getting there, just wait a bit more.
The only thing I can offer is if you're a supporter and feel unhappy with the progress, I'm more than happy to discuss a refund with you.
