The graphics look great, and overall, it’s quite a polished game for a jam—even the main menu looks super cool. Unfortunately, the "how to play" tutorial is so long that it causes a bit of confusion on its own, making it hard to quickly get a grip on the rules. Also, binding "Ctrl" to pause alongside "W" for movement is a poor choice in a browser game; I accidentally closed the tab a few times! :D
The gameplay was simple but quite satisfying, and the same goes for the music. The take on the theme was pretty straightforward, so a small minus there for the lack of creativity.
If I were to improve anything, I would simplify the rules a bit. There are a lot of introduced systems that are hard for a player to absorb—exceptionally complicated rules and a top bar for such a simple core gameplay loop.
