I managed to win, but damn the final boss had so much health! Also it threw me off that you couldn't jump on the koopas or goombas. I thought the run animation looked quite good too.
The jump to the head was one of super Mario's attacks, I wanted to avoid that in any way to make it clear that it was just a passage through a familiar environment. thanks for the comment and for playing :)
Oh that makes sense! It really is one of Mario's signature moves. It's been present in so many games up to this point I haven't thought about it that way.
