I think I mentioned before when I help test the game, the walk areas needed work and clicking stuff multiple times was a bit confusing.
I want to say a verb disc might be better, but then again the target audience is quite young... but then again a 5 year old is probably more tech savvy than me!
Maybe right click commands, look, use, talk.
Quality control is key! I'm not much of an advisor, but get people to test the game that will tell you the truth
If you check out discord, I posted some combination puzzle examples
