I'm a bit sick at the moment (wooo, post-convention flu/thing), and am not able to really concentrate enough for development. However, I've been throwing around ideas for what I want to add in the next update of Quarries of Scred, and it's always good to get these things down. This is a list I've been adding to and removing from over the last few months based on things people have said to me at cons, steam forums & twitter - as well as a bunch of evil of my own making. I don't really like to take pure suggestions from players - especially if they come from Boulder Dash, etc as I'd much rather have QoS be its own game. Some of them are super easy to implement, others are mostly wishlist type stuff for down the road (and thus, this isn't really a legally binding list, etc). Some of it might get implemented and tossed - such is development.
As said above - some of these things might turn out to be a bit too much. Extended mode is going to be a significant amount of work, but that's the one I really want to implement the most as I feel it'll reward long term players the most (and long term player satisfaction is my highest priority, really). I'd also like a better way in which to link players of QoS to Seas of Scred in order to perhaps bump sales of the latter.
Oh, and to reiterate - I've tried having the 'stand with a boulder on your head' situation, and I really don't feel its ever going to be a good fit. Whether it's a tech slot or not, I just don't think it works well within the context of QoS
