Thanks a ton for the feedback! The dash itself needs some explaining (I didn't have time to give a tutorial), but it relies on the direction you are aiming. I put it in the description, but essentially if you hold W while doing the dash, you do indeed go pretty high up! As for a cooldown, it falls under the same umbrella (I reaaaallyy wish I had a tutorial), but once your timer falls bellow 15 seconds, you can no longer dash.
Thanks a ton for the genuine feedback! I'll be sure to write all of this down and learn from them <3
