I'm interested in learning this game sometime, seems fun, how should I go about learning NMG as a noob/beginner?
Welcome to the community! I hope you have fun speedrunning Robot 64!
I heavily recommend that you master movement first. There are plenty of glitches in this game. Some are really easy to do, others not so much. But, movement is one of, if not THE most important thing in this same. You can get a really good time under 20 minutes using no glitches as proven by Ioffs https://www.speedrun.com/robot64ce/runs/z5ejjenz
If you want an awesome guide for a no glitches route, I would recommend you @Siblits guide. This guide is great for movement. It's simple and easy. And remember GET MOVEMENT DOWN
After you get movement down, I recommend learning token cancel. Once again, MASTER token cancel before you move on to another glitch. If you have any questions you can try to contact the following people, as they have way more experience / knowledge of the game than I do, and will probably give you better tips. [These people are people who generally answer most of the questions in the threads @sage211 knows a lot, but he isn't as active as other people]
@Parimatch
Have fun! If you have any questions feel free to ask them in the forums!
