You are lost. Alone. Searching for yourself. You don't see far. In fact, you see nothing at all. But you hear things... drops; water flowing; rocks falling, rolling... and a bell. Souvenirs is a 2D platformer where you don't see the environment directly. You have to use sounds to get a glimpse of your surroundings.
This is a alpha build containing the whole game in its current state. If you try it, please send me some feedback so I can improve it. Extract the content of the archive into a folder (you may need to install p7Zip to do so). Right click on the file you want to launch (the .x86 for 32bit operating system, the .x86_64 for 64bit operating system), select Properties > Permissions and check "Allow executing file as program". Then you can double click on the file to launch the game.
