User guide

It is all the bosses in a normal game of Cave Story in a row.

You can swap weapons, get missles, and health powerups at any point between bosses that you would be able to in a normal game.

You can choose between the normal ending, and the good ending based upon your choices to get the tow rope, booster 2.0 and fight ma pignon.

At the start of the game you get the clock, but you only keep it for the good ending.

If you want to record times for beating the normal ending take note of the clock when it says "defeated undead core" after that, it'll disappear.
