Yeah we had a similar problem in our game where people were wondering how to move the key into the lock in the first room, definitely feel like we should have threw a key into the very first room, or put the purple particles on it to indicate which power is supposed to be used. Everyone I got feedback from said they tried to pick it up, which duh it's a VR game, why wouldn't you try to pick it up lol.
Can you check out my team's game as well? We only have 4 ratings right now: https://symbioticparker.itch.io/a-wizards-wand
