Aww thank you! We're really happy you like it!
We haven't formally announced anything yet but we plan to release the soundtrack on Bandcamp and here on itch once the full game is done (besides also posting it on Soundcloud). And thanks for your support we really appreciate that you want to purchase it!
If everything goes according to plan, part 2 and the soundtrack should be released by the end of this month. So it shouldn't be much more of a wait now.
We hope you'll enjoy the second half as well and thanks for playing <3
