Dawg PLEASE put the OST on a streaming service of some type. I just hate having to download each song individually.
That aside, the music feels a little disjunct. like they don't all feel like the fit together in a game. bad guys wanna fight sound rough too. A ton of dissonant notes made it a little hard to listen to. Without an explanation for why you chose to do this, I just have to go on vibes.
The shop theme is also little harsh with no release on many of the instruments. If this was an artistic choice, tell me why you chose to do it.
Overall, it is a little rough around the edges and could really use some descriptions and explanations beyond just where they take place in the game.
