No problem.
I will be sharing how to create a breakable platform in the 'creating obstacles' lesson. I can also include the slippery puddles mechanic in that lesson, too. It will be a good example of using triggers to create unique mechanics, in fact.
There will be a very in-depth lesson on the Platformer Plus states (such as dashing) and how to tweak them to make your game more unique. The Player Move-set will likely end up being covered over multiple lessons because there is so much going on with that element of game design.
