Yeah we got aware of the bugs. And we realized how unclear the game was when we showed it to people x) Thank you for bringing these to our attention! We definitely want to take some time to polish the game more.
If the blue gem started glowing when it was time to apply it, I think it would be really helpful instead of having to check at every step. Just a suggestion. :)
Good idea! The plan was to have the messages on the phone actually give you hints too, and gives you the possibility to look back at the history of messages to see what you needed to do after the game understand you're getting stuck
