Thanks for the feedback, I'm glad you appreciated the changes :)
I'll probably add a few controls for PC. As for the soundtrack, I definitely plan to add more but I'm waiting to really lock down the core concept of the game before adding the finishing touches (like music, refined UI and improved assets). I might still go for a few placeholder sountracks in the meantime if I find some. Ideally I would have one soundtrack per sector to set a unique tone for each.
Thanks for playing (again) !
