OK, I guess
1. Moving mouse to the edges of the screen to rotate the camera? FRUSTRATING! OK, I know you can't use the mouse to rotate the camera; you CAN however include different keys functions, for example, instead of strafing, rotating.
2. 2GB of RAM recommended?! WHAT. THE. HELL. Well, true, I played only the first level but I've seen only about 20MB of RAM usage in that bottom right corner... or I guess it actually tells something else?
3. "Decent graphics card"? For what? Flash doesn't use hardware acceleration to render 3d; it only uses a processor. ONLY.
I would play more then 5 min. but that camera control was so irritating...
