I gave this game a shot, and I don't know if I was bugged or what, but i wasn't able to get past the first Pyramid puzzle. I could only find one of the tablets, and even when lined up properly (or at least I'm pretty sure they're lined up), I wasn't get any lights or anything come up.
The only other problem I had was the first time I started, I dropped the initial diamond too quickly and it disappeared and didn't trigger the next part of the game. Quitting and restarting fixed that, however.
Also, and this is more of just a through/idea: While I know the main catering of this game is male to female, an alternate start could be female to more feminine female instead? As a woman, the male start doesn't do much for me (not that I'm against it), but it'd be nice to enjoy just the more expansion-oriented parts instead (then again, maybe that's the focus of the latter parts of the game I wasn't able to reach).
For the record, I was playing this on Quest 2.
Thank you for your feedback! The puzzle does have a bug which I think I've fixed. I will release the update this week. It also includes an object respawn in case something falls (or is thrown) out of the play area.
As for your request on the expansion parts only - thank you it's a great idea - I plan to include a "reset+" option in the future which will jump to the expansion content. But I'm focusing on getting the PC version out next, so this is still a few months away.
