Happy you enjoyed it! Wouldn't hurt to give the super jump a better area to learn in so will keep it in mind for the future, same with your other bits of feedback. Thank you for checking out the demo!
Maybe making it a double jump, or even a triple jump could be good ? I know it's more basic but it works ! Or, make the jump always the same height, with the possibility to charge it before taking off, to go higher (kinda like Baptiste's superjump mechanic in overwatch), or even a mix of the double/triple jump + a mechanic to charge the jump to go higher !! (That could give more diversity and decision making during the fights !)
