Professor Sinister Tips and Tricks

With the game finally complete, I can share some playing tips for flying around the levels in Professor Sinister like a pro.

Climbing Ladders

While approaching a ladder, hold Up (or Down if you want to descend). The Professor will grab the ladder and start climbing as he passes it. There’s no need to try and line yourself up with the ladder before pressing Up.

Quickly Ascend Ladders #1

Hold down Up and Jump at the same time while climbing a ladder for a little vertical speed boost.

Quickly Ascend Ladders #2

While approaching a ladder, jump towards it. Hold down Up when you get close to it. The Professor will grab the ladder and start ascending, bypassing the lower rungs of the ladder.

Quickly Ascend Ladders #3

While climbing a ladder, with Professor Sinister’s head roughly level with the platform you’re trying to reach, hold Left or Right and press Jump. The Professor will quickly jump off the ladder right onto the platform.

Jump Between Ladders

It’s possible to jump off one ladder while holding Up and grab another nearby ladder. You can’t complete level 7 without mastering this.

Fast Descent

You can jump from one platform to a lower platform instead of descending a ladder or dropping down (which would eliminate horizontal movement).

Bouncing Descent

You can bounce off platforms or the level walls to get quickly from one place to another.

Jump Through Platforms

You can bypass much of level 7 by jumping through the little platform to the right when you start. Walk up to it, hold Right and press Jump. Now you can skip to those last few eggs.


The tricks above exploit the way the game’s engine works in order to zip around the levels more quickly. These are techniques that you are encouraged to use, particularly in later levels as the game gets increasingly difficult.

The cheat codes here are not encouraged and may spoil your enjoyment of the game.

To enter a cheat code:
