Theme of Arcaza: The sound you create right off the bat is unique and captures the listener’s interest. This works very well as a theme because it combines both electronic and acoustic sounds that define your soundtrack. This track definitely has the vibe of Aquatic Ambience while putting an Arcaza sound to it and definitely sets a chill but underlyingly intense mood. It’s a really cool track!
Beelzebub’s Reprizal: I like your alternation between the two minor chords as it makes this track feel dark and ominous. But your lead brass comes in adding a sinister quality with the rising melody. This is a solid theme for the main antagonist of your game.
A Hero’s Call: The use of the I-bVI progression at the beginning gives spiritual vibes and the wind melody gives direction leading into the march section. I think this is a great way to transition from the beginning to the rock section while keeping it sounding cohesive. Your brass melody with leaps of 4ths and 5ths sounds so triumphant and really nails home that this is the song of the hero. I also like that you put a true ending on when you had the opportunity to loop it. Outros can be difficult and you were able to efficiently tack one on that sounded like a conclusion to the rest of the track. This is my favorite of all your tracks!
Temple of Sumaltar and Temple of Wingtall: The ambience of these tracks is very well done. I imagine these tracks would feel right at home in PS1 era adventure games.
Face Off with Beelzebub: You show off your hard rock chops in this piece and it fits perfectly! This is a very high quality track that has a strong melody and a lot of variation that could make a long boss battle fun and interesting the entire time.
Overall: You have a real knack for strong melody writing! Every track here has a solid melody that makes sense, is easily followable by the listener, and is supported by the harmony without feeling too predictable. This is a fun soundtrack and it would be really cool to hear more music from the world you have created! Great job and thank you for sharing!
