Been playing the new update for a while - I think the balancing is done quite well now. Great work - I love "One-weapon" mods like this, alongside Combined Arms and Space Hunter.
Only thing that could use some work (That I can currently think of) is the fullscreen HUD. Not only is it rather sparse, but it appears off-center if your HUD settings aren't set exactly. (This issue is particularly bad on 16:10 resolutions like the 1280x800 Steam Deck screen)
Just a question - is the player meant to spawn with Slug Shot by default? Since there are Slugshot pickups in the world but Spawn with Slugshot is ON by default in the options, at least it was when I first played this mod. Just curious as to whether that was intentional or not.
