On game two or three, go to the maze in the Black Castle. One screen left of the first maze screen will flicker if you carry an object in there meaning one thing, there's ANOTHER object in there. At the bottom center of this room is a closed off cubicle, use the bridge to get in there and you should pick up a ''dot''. Carry this to the screen just above the catacombs (one screen down and to the right of the Gold Castle) and be careful not to lose it as it's the same color as the outside ground. Drop it there and bring two other items onto the screen, run right through the line on the right side of the screen and witness the first ever Easter Egg.

Colour Warps
At the information screen that has the mini breakout game at the bottom right that is displayed before each level, a prompt on the bottom displaying colour warp and a series of zeros. Move left or right to change the highlighted number to what you want and press the fire/jump button to set for level warps. They vary (from what I know) as Red, Yellow, Green, Aqua Warps and are displayed at the top of the same screen when you beat certain levels.
Red Warp - 23 - Warp to level 4.

Warp to Level 5

See the Designer's Credit
In Level 5, get the hat and enter the door where Berthilda the witch is flying around. Destroy her and then go over to the corner where she was, and jump. The initials FXL will come up at the lower-right part of the screen. Those are the initials of one of Crystal Castles's designers, Franz Lanziger.
See the word ATARI
Jump
one hundred or more times in the front corner of the very first level. Losing a life doesn't break up your number of jumps. Now, clear the whole level of the gems and at the beginning of Level 2, a banner that says ''ATARI'' will appear.
Secret Warp
In Level 5, go to the upper-left corner of the maze and jump. You'll be instantly transported to Level 7.
