Thanks so much for all the feedback! Working on most of this now. Not sure exactly what you mean with this point about the disarm - it's supposed to have 3 fixed uses per level, but you can freely switch between using disarm and probes/scanner whenever.
Ahh, I know what's the issue with Disarm now. The problem is it doesn't refresh properly - when I end with 1 Disarm on a level, then I get 2 on the next one, instead of the full 3. Which I assume is the intended behavior - so if you don't use them, they're essentially wasted for you for the next game. Or at least it seems to behave that way for me.
I also second the multiple flag types that were mentioned above; one for each type of mine would be great but might be an unnecessary overkill to cycle through them.
Ah, yeah it's supposed to reset *to* 3 uses each level, so you can never have more than 3 and any you don't use are wasted. Will think about how to make that clearer.
Current plan for flags is just to let you click a mine in the infocenter panel to change your flag icon to that mine, but I still have to actually implement that so we'll see how it ends up haha.
