But here I go again...
Since no one has written solutions for these levels, why not trying to make a video for it?
I tried, but the video doesn't work. Too long? I had to save and reload the game a lot. Proccessor couldn't follow anymore?
Now I decide to make a video for a small part in these levels.
In the level, I walk across, and I get 1 stinker across. For the other 2 or 3 stinker you have to do the same.
You need to same the game over and over again to be sure you or a stinker aren't hit by a spike.
The video for level 2 is ready
