I've written up a text guide to cover some basics of conc for those looking to learn, plus some tips to hopefully give improving players something to think about. The current (early) version can be found here:
Conc Guide v1.0
Any feedback is welcome, it's a bit long to read in one sitting but should be good to read in parts while you learn. This will all be supplemented by tutorial jumps/videos later on in development, so should be considered a starting point for now.
Feel free to ask any extra questions in #conc-general on discord, everyone's quite willing to help and show how things are done etc.
edit: I should have added this earlier, but Kanin has a YouTube channel with a few playthroughs of maps which might prove helpful by seeing things 'in action' from beginner stuff to harder content.
