I have the same problem. No sound also. Anyone know the cause?
edit: well i guess early chapters were a bit bugged. Voice came back for some scenes later on and the config window was fixed. Still no BGM though. On another note, looking at the walkthrough, there seems to be so many routes to the game which is great and all, but I think the dev should focus on just a few first and then add other routes later on (assuming that speeds up the releases). Game could use a bit more CGs and upgrade the character portraits to better match the sex scene artwork. Great game though. Looking forward to updates!
