Try holding down shift to give Quinn a running start.
We’re working on a patch at the moment to update the controls page to let players know that they can hold shift to run.
I completed the game. It's a cute little game, although the controls are a bit frustrating.
Thanks so much! Happy you liked our game. We’re a group of student devs so we aren’t too familiar with (proper) key binding. We were also trying to experiment with implementing different mechanics with this game. We’ll work on a more streamlined set of controls for our next game :) thanks for the feedback!
