Really nice platformer , the pixel art is top notch ! Well chosen music as well ,everything clicks together very well , managed to get to the end . The difficulty is just about right as well. Good amount of polish .
A little feedback I found out about the wall jump by just trying ,but it wasn't addressed (I was scratching my head behind the first gate when I thought I was stuck). Also , red colour for platform gave me more of a "danger ,don't step on ", rather then it is usable ( i jumped on it at the end anyway haha ) .
Overall, very good work ,you got my rating! 😎
