This is an interesting take on a 3D platformer, and the idea of exploring for the upgrades you need makes sense. The movement system is also interesting, though you could explain it a bit better (the ability to instantly stop mid-air is essential, and I'm still not sure what the "launch chicken" part is for). However, I think there are some issues with the progression overall:
SPOILERS:
When I first started I exited the restaurant before talking to Squandrick, and when the cutscene started I was afraid I missed something so I quit and restarted. Then when I got into the open area I started by going up the volcano, and when I got the upgrade not only could I not figure out how to use it (I see how it's in the instructions but even the character saying "use left click or left trigger" would help), it seemed to remove my ability to jump. I wasn't sure if that was intentional (I was using controller if that matters), but I couldn't get back to the mainland without that, so I quit and restarted again. Then I got across the bridge by jumping around the pillar of goo, got the climbing and water powers, got to the endgame, and then couldn't figure out how to get the blunk--I'm assuming there was a powerup I missed that was supposed to let me touch goo, but that wasn't signposted at all, so I had to quit there.
