Distant cousin of minesweeper, works fine with touchscreens but doesn't have a great way to "mark cell as empty" using touch; double tap works but is awkward.

2d/retro Sokoban adjacent puzzler with a floor rearranging mechanic that provides significant novelty. Requires keyboard for movement, and mouse/touch for moving floor pieces. Fun but short, 7/10.

While this does respond to taps and drags properly, the UI is heavily based on the idea of left and right clicks, making touchscreen use very tiresome.

Novel 2.5D puzzler about dragging your cape thru the mud to form little paths for mud-adverse nobles. 100% playable with touch (also, mouse, KB, or gamepad).
