Thank you so much for taking time to write your feedback.
Regarding how to refill your dashes that part wasn't clear because we didn't have time to implement a way of displaying it within the game. But essentially every 3rd score you got would also give you a dash charge. Your idea with a meter to the side is a great idea, thanks for that!
We didnt really have enough time to playtest and balance everything, so I appreciate the feedback regarding it being a bit too difficult to aim, a trajectory indicatory would probably work very well.
