This was a good game, but it could be improved...
I like games like these, they give you a sense of control about everything. However I think you could add some small changes. Here is what I think:
Remove the arrows pointing to everything. They show the player exactly wher to go meaning there is no mystry as to where to click or look at.
Another idea could be if you just add items in the room that don't do anything, but lead the player off E.G thinking he has to go to this place instead of the other.
Have a look at other games like this and I'm sure you can get some inspiration. Hope I helped :)
