MidiNode

MidiNode is a spatial puzzle game about connecting scattered signal nodes into a single closed energy loop.

Each level drops you into an electronic matrix of glowing nodes. A green energy source marks your starting point. Cyan signal nodes must be linked into one continuous circuit. Red jammer nodes interfere with the flow and must be avoided. Your goal is to draw a closed loop that visits every signal node exactly once and returns energy to its source.

You have a limited time to plan your route. Tap two nodes to connect them. Tap a line to remove it. When you are ready, activate the energy wave and watch it travel through your circuit. If every node lights up and the loop closes, the level is complete.

Levels grow with more nodes and tougher jammer placements. Choose Easy, Normal, or Hard to control the time limit and the number of jammers. A Reduce Motion option shortens animations, and an optional hint mode highlights the energy source to guide new players.

MidiNode runs entirely offline. There are no accounts, no sign-ins, no ads, and no data collection. Every level is generated on your device. Settings are kept only for the current session and reset when you leave. The app does not access your camera, microphone, location, or media files.

Whether you have a few minutes or want to push through tougher levels, MidiNode offers a calm, focused puzzle experience built around the geometric beauty of closed circuits.
