The game is quite difficult, but it's great that the player can place tiles to make notes. Your game also shares some concepts with Dark Echo, but the games are very different in execution. It looks like you already know what's wrong with the game, please fix the game.
A downloadable game
Only one of the five senses
This game was created for the GMTK Game Jam. Using the jam's prompt "only one," you must navigate levels and puzzles using only one of your senses - your sense of hearing. Use sound effects to triangulate your location, mark your progress on a map, and try to reach the end goal! But watch out, things aren't always as simple as they look (or sound).
