Pen engine! So, I was messing around with pen, and then I realised how easy it is to make letters, so yay The maximum length of a line in size 2 is 28 letters
Keys allowed: abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ!?.,-_ umm, i think i'm sort of scamming you here, considering that the capital letters are the same as the lowercase letters lol
