Maybe some sort of Tutorial would be nice? I've added mouse prompts to the UI though. Maybe you don't see them that well because they blend with the UI. Thank you for your feedback and playing our game. I'm glad you liked it.
I think you can make some pop up prompts. Like, when your left weapon runs out, a hint appears saying that the right weapon is also a thing. Having some movement instead of static elements should bring attention to it.
