GENERAL TUTORIALS & LINKS
I have a forum post with some basic info about setting the game up, frequently asked questions, etc, that you should read first. You can find it here.
Your biggest focus, when starting out, should just be not dying, right? If you think the harder skips are cool & wanna try them, that's great, but you don't really have to worry about em until you're comfortable with movement in general. Also, I know some people like to do this, but I really, really don't recommend trying to learn from the record..
Learn from these links instead :)
safestrats video tutorial for any% by Applesauce. Will help you complete the run relatively speedy.
detailed video tutorial for any% by Monkiboy. For players with a higher level of skill than the previous video. It's been a few years, so it's not entirely up to date, but it covers a lot more.
brownie skip video by thebmxbandit11. Also covers sprintjumping.
naija tutorial by Uber.
alternate method for naija clips by gupop.
any% all glitches explainer by shredberg.
strategy reference and glossary by Misteur, Ikod, Crucrux, and others. Really useful if you want to browse strategy options for a specific stage or stages, and/or you want indepth explanations of some vocabulary. I can't recommend this highly enough. Note that, as of right now, it only really covers strats for the any% and dark ending categories.
