Show HN: Linux CLI game, quiz, cheatsheet and map from my mind mapping app

https://mindmapsonline.com/linux_commands_quiz
5•max002•8h ago
Im working on a mind mapping app that would allow for integration of gamification features and be nicer and easier to remember. I was missing more advanced graphics from apps and being able to treat it as my note taking and learning tool.

i.e. how (and why?) should I remember a mind map if it looks the same like all other maps and all i can do is pick couple of shapes and dashed/dotted lines?

this simply doesnt work with my brain so i decided to create something better :) map on page is a preview of this, but im curious about the quiz, typing games and cheatsheet, would love some feedback (and ideas) on such training modes!

Another thing i'd love is some comments about any features that you miss in existing mm's soft. If you're mind mapping enthusiast and interested in beta testing checkout contact form :)

p.s. last week i posted simple map, but i didnt realize i can use SHOWN HN for stuff that ive made and that lets you play with something. It just vanished down the pages so ive added new commands, modified all bad answers to be more realistic, and added some features for quiz and typing game and reposting to get proper feedback and hopefully some testers!

as well, if you're not ready to take lengthy quiz [nearly 180 questions] pick a smaller random generated subset to play with it!
