To buy potion (of any other stuff), you have to go close to the marchant (a little "buy" appears on his head), open the marchand menu (button 2), put the cursor on the potion (arrow), select it (button 1), validate the buy (button 1 again).
To drink a potion that is in your inventory, you have to open the menu (button 2), but the cursor on it (arrows), select it (button 1), validate (button 1).
Actually there is a tutorial at the beginning of the game, but it is easy to miss it.
I might have to do a proper "tutorial mod" if a lot of people are confuse with that.
The camera is a real problem for me now.
In one hand, I want the game to be playable by several people on the same screen, on the other hand the game is a 3d game and players are not necessarily close together. I am still working on it.
The game is actually slowing be cause of the music.
The music is encoded as ogg and I am using jorbis to decode it.
During the transition of the day/night the music of the day fade and the music of the night grow.
Therefore, for a few second, the two musics are decoded simultaneously -- and that is killing the performances (according to jorbis's devlopers).
In the last version, I cut that out. The transition are a little hard, but there is no more lagging because of that.
At some poing of the day, the web server has a lot of visite (some other web site), it may be because of that.
A stand-alone version of the game is now avalable.
It has been test on windows 32, windows 64, linux 32, linux 64 and mac os x.
You can download it on the game page http://shlum.wtfcontent.com/
