I can see something there, though the nature of some of the upgrades, like when you go from rotary to automated press you completely lose the ability to click to make bullets. Having both be available would be nice.
Other than that, the UI is extremely cramped, almost as if this was made for a 4k monitor, text is small, buttons are smaller, checkboxes are tiny. I couldn't even get the game to focus on some research.
Proper settings would also be nice, like the option to mute the sound. Right now all it does is cycle through the appearance.
