Thanks for so detailed reply!
Yeah the whole system of multiple dash charges with that rune is a bit messed up. We draw this "double dash" rune in the last day of submission and forgot to sign it somehow so players cant understand what it is. Other problem that we dont have required quantity of peeople who tested our game in early stage so some parts of the game feels unintuitive or strange on first glance. Your suggestion about staying at max height after taking it is actually simple and smart but sadly we could figure out it beforehand. All your notes have fair point so in future we should ask you to test our future games :)
Very happy that u enjoy playing our game and thanks for putting me on joy with your reply!
