Nailed the underwater vibe off the bat; great choice of instruments and voicings. Loving the blend of 8 and 16 bit style of instrumentation. The simpler waves contrast really well against the more FM-oriented sounds. Great use of articulation, particularly with the 8-bit stuff, as that really sets the bar for working well with standard waveforms and pushing them to their limit.
All in all, this is a collection of really solid pieces. Nice and varied, a lot of cool ideas and great executions throughout. I think my favorite of the bunch is probably Minty the Fish - I could imagine myself hearing this in so many different types of games. Great work, this was a really fun listen! :)
