It looks like a really promising replacement for SDT, however, every time I've tried a free demo I've had the experience tarnished by either animation jank, controls not working, or just incredibly frustrating bugs. I've just tried it for a third time and it's had progress that's great to see, however, it's honestly a little strange that the visual novel won't allow you to save or go back to be able to read some text you might've missed. That said, I'm happy to see they've fixed the boob hang animation weirdness, but am annoyed by the fact both the orgasm hotkeys as well as the edit character buttons in sandbox seem to be broken.
For these reasons, I have to give these developers a 6/10 which is a shame because I know if I at least had a demo that proved these issues were fixed before I start putting money towards this, I know they could easily be at least a 9/10.
