HOW I PLAYED IT: Download the project from github and played it in the Unity editor, navigate between the levels by loading each scene separately.
I really loved this game. Really creative use of the assets. The octopus is really fun to control; it was exciting being such an unwieldy space monster trying to do a delivery job.
The navigation between scenes is out of order, but otherwise the polish is good.
Great game!
I'm not sure on how the grading should apply in this case; but I'm only going to knock a single star off on polish for the fact that I had to run it in editor.
