Wow. you have no idea how happy I am to see this comment. You stated all the things that I am proud of about this game!
I use RayCast for shooting so that it hits the target right away. All the enemies (for now) die from a single hit, so you either one shot one kill or you miss entirely. There's no firing speed so you can be as fast as you want as long as you hit them. I love what you said about feeling like it's your fault when you messed up, hopefully it's from the hit or miss thing.
Glad that you enjoyed the powerups and health system. I tried to make each one as balanced as possible. clip size upgrade is my favourite, if you ever play it again, I recommend trying it.
you even noticed the running particles XD. Players generally take small things for granted, only when you make a game will you know to appreciate it. thanks. And it's good to know that hours spent on finding the right sounds was worth it :P
Thank you for playing the game and leaving a comment.
