If I was designing it, I would make the gun face the nearest bug. The difficulty of the game, at least how I see it, should be in managing the swarm, not killing the individual bugs. Good luck with it though.
firstly, the environment is really pretty and overall the graphics give the sorta goofy vibe I believe you are looking for.
secondly, for UI canvas, set it to scale with screen size instead of constant pixels. I was plaaying the game in 4k and the UI did not scale properly from the 1080p you tested it on.
thirdly, please make it an option whether or not to invert the axes, aiming is so difficult.
finally, great job, you should be proud of yourself and I cannot wait for the sequel.
