I enjoyed this game a lot.
The gameplay is quite fun. It's always a joy when you get that "ahah" moments in adventure games, and I definitely got it here.
The controls are very easy to understand. The custom cursor and the text that appears when you hover over an object helps a lot. My only real problem is that the inventory is a little hidden. I know you explained how to get to it on the game page, but it's always nice to say it again inside the game itself.
The art is awesome and the music is enjoyable. The game is very well presented, and I like how it has a custom splash screen and a custom cursor.
Overall, the game is fun. It's a little short but still very enjoyable. If you were update this, the only thing I would recommend adding is an indicator of where the inventory is.
