Alchemy - proof of concept

This is my first attempt at a rules engine.

It is only controlled with mouse. Grab objects and put them onto the environment. Don't be impatient, sometimes it takes a second more to do what's supposed to do.

It may be absolutely broken, I could finish the preparation to start adding rules, but I didn't have enough time to add a lot of them.

There are 5 kinds of potions with varying powers.
