I'm a bit lost playing this one. Gave it 20 minutes or so, but didn't come across any metroidvania upgrades or jump button. The way I figured out to play it is to build speed and then launch off slopes at angles to reach new areas. Not sure if that's intended, but, at some point, I couldn't progress anymore. Perhaps I missed something.
Hovewer, you guys did a great job at setting the scene. It looks and sounds quite nice !
