Arrow-Keys I know it's difficult because you jump creepy but it is the sense! To come in another Level wait 2 seconds and jump often (maybe press leftarrowkey also)! ***Story*** Jumpy was playing with his friend when he saw that it is almost 8 o'clock! OHNO! He would come home at 7.30 pm! Now he must be fast home to the arctic!
I know that this is not easy and not hard but this is the SENSE! It's sense that you can through walls also :) I hope you like it and I think nobody before make the sense of a platformer buggy ;)
