Massbound

Massbound is a puzzle-platformer for mobile built around a single gesture: every move costs mass. The more you move, the smaller your cube gets, and when the mass runs out the level starts over.

Swipe to move and swipe up to interact. Everything glowing green can be used, like trampolines, switches and moving platforms. Everything red takes mass away: lava drains all of it, while spikes take more or less depending on how fast they hit you.

It has two modes. Standard is the strategic one, with no lives and no checkpoints. Arcade throws random levels at you with five lives to see how far you can get.

Shown at the first Salón del Videojuego de Madrid and funded on Kickstarter with €1,122 raised. Built in Unity, with Firebase analytics from real players guiding the level difficulty.
