First time entry, first roguelike, first day!
I’ve opted for small, experimental take on the roguelike (taking a page out of Michael Brough’s 868-Hack). The primary mechanic involves switching the colour of the background to makes certain walls invisible. If you can’t see it, it can’t get in your way.
Made lots of progress on day 1, getting the basic mechanic down and adding some juicy feedback. So far, so good. Anyway, a screenshot of the work in progress.
