Those DASH and BOOST moves are meant to be limited, basically so you're forced to use them in combos with other moves. For instance, I didn't want you to easily move side to side while using BOOST because that would negate the purpose of the JUMP move. I'll be sure to revisit how those mechanics work when I get back to developing the project.
Thanks for all the good feedback, and I'm glad you had fun. You're absolutely right that the game could benefit from easing the player in. I'll be working on that very soon.
