Thank you! Glad you like it! Yes, a tutorial is needed, it's in the works :)
Yes, a separate roll/block is totally something I've considered. I'll have this as alternative but not remove the current way as it's like the smash bros games and a lot of people like it that way.
So, for the first image, you have to beat that third stage to get a 'dash' move and the second image just double jump and do a 'up+special' to do an uppercut which would be a 'third jump' and grab the ledge. but if you leave some trees intact during the fight you can climb them to make it easier :)
