Demon Castle is a Castlevania-style game for PICO-8
An evil sorcerer is trying to summon an ancient demon into the world. You are the only one who can travel to the sorcerer’s castle and prevent him from completing the summoning. Best of luck.
At the title screen, use the arrow keys to select your difficulty, then press the Z or X key to start the game.
Use the arrow keys to move, and press up or down to start climbing stairs.
Use the Z key to jump and the X key to attack with your whip.
If you prefer, you can use the C and X keys instead of Z and X.
Heart Crystal
When you defeat a level boss, it will leave this behind. Collecting it will increase your maximum health, and end the level.
Chicken
This secret snack can be found hidden in secret walls throughout the game. If you’re lucky enough to find some, your health will be fully restored.
Crypt Key
This old key has been lost for centuries. Where could it be now, and what could it unlock?
Stone of Sealing
If you are unable to stop the sorcerer, these stones will be your best chance to reverse the summoning. You should try to find as many as you can.
At the title screen, you are given the option to pick either Normal or Hard difficulty. When playing on Hard, you will start the game with less life than on Normal. You will also encounter more enemies in more difficult locations. Finally, when playing on Hard, you will not be given checkpoints throughout a level, so you will need to start the level from the beginning if you lose all your life.
Due to the size of this game, it was necessary to reduce the size of the code before the game could be released. I used the picotool library to reduce the size of the code, at the cost of readability. However, the original code, before being reduced, can be found on GitHub, here.
