SHIFT to fireball (after you get the 2nd page), WASD to move, SPACE to shoot pistol.
Game has a checkpoint system in case you die.

-- Important information --

Since I didn't get to add this, this is what the pages do in order:

    1st: true sight - allows you to see things you wouldn’t otherwise
    2nd: fireball - shift to fire
    3rd: stone skin - acid no longer burns you and incoming damage is reduced
    4th: arcane leap - double jump
    5th: dimensional door - open sealed doors

There was supposed to be a good ending, but due to lack of time the game crashes instead of triggering it, so only the bad ending is available.
