The idea is quite nice, but I couldn't play it well. It seems there is an odd offset in the mouse that does not allow me to aim properly in the left, lower left, and lower right sections.
Curious to know which browser and OS you were using so this problem does not occur with any other games we make with this game engine
I'm using Google Chrome (Version 97.0.4692.99 (Official Build) (x86_64)), on a macOS (Monterey 12.1).
