Ok, I'll have in mind the pause menu like that, I wanted to put it at the end but I felt maybe I'll break something for how tired I was yesterday.
Yeah, the sounds can be like that, I had to use some extra audio buses in the settings to lower some sounds that were quiet but in game sounded louder or more quiet than intended haha
And about the UI elements, I ran out of time, also for that I didn't put the lifes sprite but probably I'll try to do those in this 2 weeks where I can't modify the game and learn how to put those in the Godot controls, I felt those were janky but mostly because I didn't have too much time to properly learn how to use them
Also, I'll have in mind more shooting variations, 1st I have to balance the drop probability, health of enemies and damages from the game, sometimes I felt it was too hard or more easy than it should
Thanks for the feedback in the UX/UI, usually it's my weakest point in programming so I appreaciate it :D
