Level 1 is extremely easy and requires no prior gameplay experience to beat it. It is almost impossible to lose unintentionally.
To reach the end of the level, simply jump over the holes or just walk around and avoid them.
Level 1 is one of the few levels that can be beaten easily without jumping. If using the Pastafarian or the Bunny, it is not even necessary to press any keys, except to jump over the barrier at the beginning.
Level 1, along with Launch Site C, is one of the two (or three if Memory Evaluation, part 7 has one) levels in the game that has barrier tiles. They serve the purpose of stopping the character. In this particular barrier, there will be a message explaining the controls appears on the screen. On the top of the screen, it will say:
Attention, citizens. This area is restricted. For your own safety turn around now.
While the bottom of the level reads:
Press up or space to jump.
This is the only 'tutorial' or gameplay instruction in the game, as the controls are quite simple and intuitive.
If you are quick, then you can walk around the barrier and you don't need to press the jump button.
