I tried it.

1. Supply OpenAL with the package. I, for example, don't have it installed on my WinXP, so I was playing with no sound.

2. The volumetric fog isn't visible in the bottom part of the screen (see 1, 2, 3).
Sempron 2400+, GeForceFX 5200.

3. With no sound it's very hard to see if you hit the monster or not.

4. Shouldn't be this dude textured somehow?

5. Solutions for the edge-of-level could include: a) impassabe cliffs/abysses at the edges of the landscape (too high/wide to pass even by flying) b) endless sea (level=island)

6. It could help if your game spewed out a log file.[/url]
