Hello! I would like to leave some remarks.
1. Only the numpad is working.
2. The key sprite to get the Proton Gun isn't showing up, but it's working. After picking it up in the bathroom, enter the last room in the upper corridor on the right.
3. When sand is taken from the potted plant, the fireplace goes out and a text appears. But the text is starting automatically for bug reasons.
This is not a complete game, but a concept. Enjoy!
