Fun little game I found online.
This game rocks. If you haven't played it yet then play it! You won't be disappointed.
I can't figure out what to freakin' do >.<

I found Horsehoe #2 and #3, 3 apples, a carrot, and a pair of pliers or whatever. I found the key to unlock the paper. I figured the graph is the heating cycle for the forge, and so I tried putting a horseshoe in there and punching in that heating cycle. Nothing.

Check out that kiln closely. Also, be sure you click around, try different items on things. Feed your pony before it starves. >.>

I just played through the game again and never fed the pony -- it does not starve! You lie.

You can't play through it without feeding it. You lie.

I guess you have to feed it magic oats and magic stone water, but I would have thought it would starve before then. :-(
I was expecting "But I ated it"
