So recently, I found out that if you press Enter and 4, you skip instantly to the last level. Is this allowed? I'm assuming this isn't allowed, but I'm asking for verification.

no that would not be allowed

Doesn't even work for me. Which version are you playing? Thought it would be useful for practicing later levels if enter+3 also would send you to level 3

@IlSocioLoZio I'm playing the version that was provided in the recourses tab. I think the function wasn't coded properly, because sometimes the game doesn't register the inputs. It's either that, or I'm doing it incorrectly.
