No tutorial or game manual. No setup for mouse movement speed - hard to look around, or other common options. No zoom/overview. No guide/arrow/pointer. No quick-save or even save-game. Clumsy keyboard movement instead of click to move.
In general I liked the game pretty much, but as soon as I reached The Loom, my PC couldn't handle it (no matter what settings I used), even if before that I was running all on Maximum-Medium settings just fine. So I couldn't push myself through it, it's too frustrating to play this in 10-15 FPS. Disappointing.
