The aesthetics and art looked pretty cool and the procedural generation was pretty neat, but definitely had some flaws. First off, the mouse wasnt locked to the screen, so it really threw me off with my mouse sensitivity. The enemies for me were either buggy or not totally functional? Sometimes they would shoot at me sometimes not. And honestly, I didn't really understand a clear "goal" to achieve so I kinda just wandered aimlessly for 5 minutes, which ended up being a little dull.
The theming with "Joined Together" also feels a bit vague as well. Overall though, this could be refined into something really cool with the procedural generation, maybe some kind of roguelike?
