Paper Mew, a Studio for Small Puzzles

Field notes

The studio's first named project is Fill Trail, an iOS puzzle game still marked as in development. Its central rule is unusually concrete: draw one continuous trail that fills every space, while each local choice affects the remaining route. The homepage also articulates a broader design system built around grids, lines, clear rules, and time to revise an answer. No release date, demo, price, or playable build is visible in the supplied extract.
