Played and won. Found 3 diamonds. Did not solve the skull.
For awhile there I thought I had to use the flashlight to shine on every empty square in the house for an invisible object. Did not know it was merely a weapon. Might be an idea for future game to have an invisible object that can only be seen with the flashlight.
"You have escaped the spooky house."
Here is $2 for you. Very enjoyable. Please keep me posted to any future games you write.
