Hi thanks for playing! The gun is actually firing at properly, it uses hitscans with tracer rounds every so often (the tracers are just eye candy). Not sure if you're new to shooters, but think of how in most FPS games with hitscans, you ocassionally see tracers while firing continously. There are sparks particle effects on impact, but the retro shader does make it hard to see things in the distance and the enemies don't give much feedback to damage.
Yeah I added a tell that the elite enemies and the boss are gonna dash by kneeling for a second before, but again, it might be a bit hard to notice in the distance or at all with the pace of the game. Perhaps I could've made a more noticable tell. Some AI and animation jank on my behalf also means they may dash without that or while moving towards you (which isn't intended) .-.
