In the beginning, it was kind of confusing on what to do. I think the theme was shown well, but I feel like it would have been better if there was a tutorial. (There was a lot of boxes).
The audio was good! The pixel art was nice, and I think that this could turn out to be a cool little shooter with the ideas fleshed out.
Overall, I had trouble understanding the concept in the beginning, but then it became clear. Overall interesting concept!
If you have time, I would appreciate if you could take a look at my submission!
