I like the concept. I wasn't able to switch weapons using the number keys. Perhaps you configured them for the numeric keypad, which my keyboard doesn't have, or maybe the weapons need to be found first and I didn't manage to locate them. Overall, very good game!

Hey! I'm so glad you enjoyed the game!
Well, you're right, I did program the swap with the number keys (1,2,3...), but I developed the game in my laptop, so I can't test with other keyboards, like a full-size with number pad separated. My apologies!
To get other instruments, you need to defeat the boss at the final of the stage, and they appear in HUD in the corner of the screen. Only the first instrument disappears after you take the second, a little feature that I implemented for the initial weapon.
Thank you so much for the feedback! Do you have a suggestion for another key to switch weapons?
