I really enjoyed playing that - escape room style games are just down my street!
I did find it a little easy, but I understand that it has be made quite easy generally for a game Jam as people have to rate a lot of games so it can't be too time consuming as people might get annoyed by that - it's a hard balancing act... I did finish it on the 2nd go. For me it could've done with more challenging puzzles, but it's hard to gauge the difficulty level on these things as the audience level is so varied.
I really liked the look and feel of the environments, you did a great job there!
Kudos for adding hand tracking, and I see that the tracking implementation would have been quite challenging, however it might have been good to have the option to use the controllers too. Not that it was down to your implementation, but hand tracking in general I did find it really hard to pick things up and press the buttons on the table.
All in all - great entry, I really enjoyed playing it, nice style and presentation.
