Boxgame is a puzzle platformer in which gravity is ruled by big, transparent boxes in the centre of each level. Jumping off a ledge will result in some crazy re-orientation, after which you most likely won’t be standing on the same plane anymore.
Which, of course, leads to lots of lovely puzzles. Sophie has clearly put a ton of thought into some of the solutions (especially towards the end) and, while it never gets incredibly taxing, you’ll definitely need to use your brain! She also promises new levels soon to add to the fourteen already there, so it will worth going back to again once she adds the new content.
