Hello Kurt.
I really like the game, but I really miss the information what the modifiers are doing. Many of them have no effect on numbers, or the effect is contradictory to the description.
For example "Pi" should decrease damage, but it randomly increase or decrease "Approximate damage per bullet".
I quickly build a prototype to show that accurate weapon info might be easy to add: https://jakub.bandola.cz/wa/ship_shooter you can check the source code at https://jakub.bandola.cz/wa/ship_shooter/gun.rs, I did not try to polish the mechanic, or implement them all, just to be an example.
