Woah this was one heck of an adventure! I was not expecting a boss fight with multiple stages lol. The thing that sold me the most was the atmosphere, seeing the background of those eye robots running rampant everywhere in a parallax view kept me very engaged with the story.
For the second stage, maybe have an indication that we need to keep running because when I was running it felt like an endless loop and I thought I had to get hit by those bushes to progress. And I think the up key doesn't work for jumping. Other than that, awesome game!
