It's a flight sim. You don't use the mouse in the game though. You're stuck with Up doing the opposite of what you expect it to, and constantly crashing into the ground. not to mention that unlike Descent, this game has an annoying desire to let you roll and then force you upside-down or upright.
So, playing the game is fantastic... Till you die. Then (on my 1-year-old quad-core i7 machine) it takes FIFTY SECONDS for the screen to go completely red as you die. (The going red is normal... the amount of time, I imagine, is absolutely not.) It makes it nearly unplayable on a challenging difficulty, and something really needs to be done to fix this.
