Great game and good level design. The visuals, while simple, look really clean too. My only issue is that I find the keybind for crouching a bit awkward to use with WASD (also crtl + w, s, and d all work in browser). It feels better with arrow keys, but as someone who's more used to WASD controls, it'd be nice to have an alternate key that feels better with it. Good job on this!
