Really good job! And your first gamejam at that! Very impressive. The game felt great to speedrun, just holding right and no breaks. At first I was wondering why I wasn't jumping that high, but realized I had hold the jump button a bit longer to jump higher. Whilst playing I was wondering how exactly the limitation was implemented which after reading the description on the submission makes sense to me although it would have been nice if you figured out a way to implement it as a mechanic somehow. Excellent job and hope to see your future gamejams too ;)
