Hey there,
about the first part you wrote, all that was given birth because of the bad level design. Stopping and returning was supposed to be able in some parts, but that was just if you would be really good.
Running wasnt supposed to be mandatory, it was supposed to be a "too fast" thing, which you use to accelerate. Holding the run button was supposed to be a short thing, of some seconds. I just didnt get the numbers right in time for the runspeed and walkspeed.
Sorry for the inconvenience that all that caused you. I took notes, and I will do better next time.
Thank you for playing, and even more thank you for taking your time to write all this!
See you at the next game jam :D
