First of all, thank so much for taking your time to do this, I really apreciate! This will help me a lot fot my future projects...
I agree completely with everything you said, especially the part about the difference of difficulty and punishment. I had never actually thought it or heard anyone express it, in that way. I will definetely keep that in mind, Thank you! And yes, after submitting I saw that there was a problem with the double-jumping code, not always registering W or UP_ARROW presses :(
Again, Thank you so much! I learned a lot about level design, I will definetely save thi comment for further use. I'll try to implement as much you have said either in this project after the jam or future projects.
Thank you again!
