Would have been fun, but for bugs and items which are basically impossible to find without a walkthrough.
Others have already pointed out that items such as the screwdriver are extremely hard to see.
However, I also encountered a game-breaking bug which does not seem to have been raised before. In room AB, you are supposed to find the red key after using the lantern to illuminate the dark hole. In my first load of the game, the lantern was stuck at the bottom centre of the screen so I couldn't raise it to find the key. After I refreshed, the lantern was movable but the red key was not there. It is not in my hand or anywhere in my inventory. It has not turned up in room AB or anywhere else after multiple refreshes. I cannot complete the game because of this.
