Thank you!
Looks like I should've taken some more time to have the game mechanics be explained - the bullets themselves don't deal damage, but instead change Clover's color according to the color of the attack he was hit with. If Clover is standing on his own color, he'll take damage.
And glad you enjoyed the starting location! Really wanted to make the player intrigued by what's going on around them at the start. The dialogue is understandable, I could've probably implemented that in the I had left, admittedly!
The reticle is also a good point, actually - didn't think of that, and that could've helped quite a bit in the chaos!
As for the versions - I have little experience with WebGL, and combined with some poorly optimized segments and a bit of spaghetti code (rendering a 1x1 camera per enemy to get their floor color every single frame who?) it's understandable that it can lag in the browser. Glad the downloadable for Windows worked fine for you, though! I do wonder why strafing doesn't work with Firefox on Linux - I did use Unity's new Input System, so maybe that's the culprit?
Again, thank you for all the feedback and testing! Useful info. Glad you enjoyed!
