A few words about the game soundtrack. As the game is developing, it is a really a challenge to write music for a lot of tracks. At this moment the soundtrack is made in Logic Pro using several Garageband loops. When a soundtrack is prepared, it is divided into parts which can be played sequentially or can be looped. One music concept determines the actual soundtrack for the particular tunnel track. The sound loops are ordered to the different tracks, when you can't go through the track within a specified time - which is actually the length of the loop, the loop is repeated. When the track editor feature will be implemented, you can choose a music concept from a few predefined ones and you can freely mix the loops for each track stage.
