Ahh, thanks. At least it's a mistake I'll only make once!
Loving the tension and feel of the game. I've jumped out of my skin several times when encountering a robot I didn't expect. Brief forays outdoors really add to the atmostphere, with the droning of the large transporters flying overhead - and launching robots at you while you're on a tower, too!
I plan to add a simpler gameplay mode. The whole plan is to separate checkpoint/run based gameplay setting from gameplay complexity making it possible to play simpler gameplay run-based (permadeath).
Another thing that is going to happen is extended play/endless mode. This will enforce current roguelite mode rules, though. With map, additional devices and permadeath.
