@Donut Master, I recommend reading through the encyclopaedia. I didn't do it until half way in (16-ish hours) and ended up learning a lot of valuable stuff, including how to split stacks of items.
This is, without a doubt, the best flash game I ever played. I tested the beta (all three chapters together in one) and was absolutely addicted. The amount of detail and work put into this is evident straight from the beginning. It has the quality of a production-style RPG game. Overall, I ended up putting about 35 hours into it and loved every second of it.
Definitely unique. Didn't understand it at the beginning, even with the tutorial, but caught on quickly. Controls felt a little off, but still had fun with it.
