Pixel Flow

A puzzle shooter with an unusual control layer: your cannons sit on a conveyor belt that moves them continuously, so you choose which cannon to place and where, but not when it will be pointing at the thing you want to hit. Timing is a consequence of placement rather than an input. That constraint is what makes it a puzzle. Boards are made of coloured blocks that only the matching cannon can clear, and because the belt keeps moving, the order in which you place cannons determines which shots are possible later. A placement that solves the left side immediately can make the right side unreachable for the rest of the level — which is the kind of mistake the game is built around, and it is always visible in advance if you look. Levels are a couple of minutes and there is no time pressure within them, which suits a game where the correct move is frequently to wait. The presentation is clean and the colour coding is unambiguous, which a matching puzzle must get right. It plays with taps on a phone and needs nothing from the hardware.
