Thanks for the compilation, Tyrant.
A small U/X suggestion based on my recent experiences with DRL:
It would be convenient if we had a way to show how much ammo is left in your inventory for the current weapon you're wielding. Feels like there's space to the right of the weapon itself, at least.
I know you can open the menu to look, but not having to stop the action to look and keep track may make gameplay flow better, especially with ammo-hungry stuff like rapids.
There's a lot to go through and respond to here, but for the moment, +1 to having an upgrade to the basic pistol that isn't a special drop you could never see in a given run.
EDIT: Also, after once again staying up until almost 3 AM playing the game, I think it'd be -extremely- helpful to have a clock display somewhere >~<
It can maybe be toggled or something but it'd certainly help with keeping track of time, especially when playing in fullscreen.
ToME has this as an add-on and it's probably the only reason I don't stay awake playing until ungodly hours
Having an ammo display on the UI bar would be convenient and there is certainly space for it. Main issue is ammo boxes and other weapons of the same type with ammo in them, but I would imagine that it wouldn't count them since that isn't ammo you can readily reload with. And if you have an ammo box equipped, it could instead show the ammo left in it.
As for a time display, I personally don't see much use for it, but it is one of those "sure why not" things, as long as there's a clean spot in the UI to fit it in (and it of course isn't too much a pain to program in).
Updated the OPs to include this and a more up-to-date bug list.
