I beta tested this game.
This game has a utilitarian interface, but don't let that fool you: this is a seriously great game.
Your magical witch house is broken, and you need to fix it. You have an inventory (even though it's web based), and you have the power to alter the elements of various inventory elements.
It has a cheerful backstory. Different items you carry interact with each other.
The various interactions are fiddly sometimes, and perhaps even unfair; but somehow everything gelled for me in a great way. Not everyone may feel the same.
