Things work mechanically, so you seem to have that. Now to expand it to another room or a door so the character can get out or do something else.
I had a key, but no where to use it? I also found that the inventory items were really hard to see -they are not very visible on the background.
This is good for a school project- probably there was a deadline which made it time sensitive to do more. But make the revisions I noted and you could have a whole game here. Thanks for letting us see your work.
