A game that runs based on echo signals, i guess. Well, I'll try to describe it in short words. You can scan the cube to get a echo maps, the whiter the color the higher the score, but some lower your score and SAN value . So use echo and shop wisely. A bit like a combination of Gold Miner and B-scan ultrasound? Well, that's it. The word inspires a lot. The theme "Signal" evokes a cascade of associations. Starting from its most fundamental meaning, one can branch out to explore the fascinating steps of its generation, origin, development, and transmission. Ultimately, I chose to anchor my design by focusing on the processing of that signal.
