I had the bonuses from completing all three bosses on easy difficulty, after restarting the game they're all gone and when I try to enter a room it just starts the fight. Do I have to defeat all the bosses again to get my bonuses back?

if i didnt have to break my fingers mashing the left mouse button

This is a story about a boss whose eyes, heart, and brain are combined. Once the game is over, the character behaves as if it is lagging and cannot jump satisfactorily. Is there any way to avoid this?

* If you take a slow motion item after defeating a part in the final boss, it will no longer be in slow motion and the effect will remain. * If a part of the boss is destroyed during the slow motion, the slow motion will not end. * It could set the gamepad to key bindings, but in that case it did not work....

Dying to the final boss will sometimes cause you to get stuck in the death screen. having to pause, quit, and reload the game gets kinda annoying on hard.
