I've recorded a few videos for levels people ask for hints for. You'll find them in the videos section, but I've also made this guide to make them easier to find.
This is not a comprehensive guide, I just record new videos as I observe people ask for help with a level that others haven't helped out with yet.

Goes without saying that all these videos are major spoilers. Consider just watching the first few seconds to get a hint about how to start instead of spoiling the entire level.

If anyone makes a comprehensive guide, feel free to use my videos instead of rerecording them yourself if you prefer.
