Hi there, I enjoyed playing your game a few days ago, despite taking some time to get used to the 'lamp', 'potion' and 'briefly showing the level blocks before they turn invisible' mechanics.
I must confess, though, that I cheated on the last level by taking a screenshot of it before playing it for the 4th of 5th time, as I was just too impatient to memorise the layout completely before going in.
It seems your game supports the act of taking screenshots, as Agatha's health meter does not start decreasing until AFTER you start moving her around, which is quite helpful :p
