This is a site-locked game demo made back in 2010. We decided that even if the full game never gets released, people should at least get to see what we've made.
You can click to just walk around but to interact you need to hold the mouse button down. If you've clicked to enter another room you can click again to skip the walking animation. You can also click to skip dialogue.
Roll your mouse over the upper right corner to find three menu items. The question mark shows you the instructions, the m opens the options menu and the i opens your inventory. Don't forget to try combining items.
