The upgrades and restore orbs (restorbs?) were such a treat to find! It felt like right when I needed energy or hp, I got what I needed. And the jump upgrade (jumpgrade?) had me thinking where I might be able to go back and reach with my new power.
I did get lost often, and I couldn't quite figure out where I had or hadn't been. Some of the larger landmarks/unique backgrounds helped.
I also couldn't figure out if there was a trick to the super jump, like a material I was standing on, or if I was moving, but bunny hopping all over the map was no issue, and actually quite fun!
Great work!
