Hey! Thank you for your time. No, of course not! You can jump in using DASH - hold down the [W] key, select the direction, and release [W]. Sorry, I didn't explain it very well in the tutorial, I already working on small update!
Great! I wanted pressing DASH to switch us to aiming mode, and releasing it to make us jump in the selected direction. Just like shooting a bow in games, but I see that this is a problem for many, and I need to think of another solution. And I haven't implemented the control change in the game yet. It's a little easier on the gamepad (which doesn't have full support yet).
And yes, DASH is higher than normal JUMP.
