Okay, Let’s Begin: This is a really cool opening and sets the tone for a mechanical heavy-duty type of vibe which works for a tank game. The jazzy melody reminds me of De Blob’s jazzy soundtrack and adds a layer to what you have that adds some optimism as if you are closer to setting forth on your quest.
Your Room: This vibe is so chill yet suspenseful at the same time. Your jazzy synth/organ chords are very well-selected and evoke a lot of emotion, especially when you introduce the non-diatonic minor chord. I really like the sound you created here.
A Little Over a Week: This is a really fun theme and I think it would absolutely go along with a tank game very well since it has the intensity, but it keeps going and never has a point where the energy fades.
You Can Rest For Now, but the Clock Keeps Ticking: The harmony that you use is the perfect way that you are telling the player that things are okay while at the same time including warnings and hints that they may be wasting time. I love it!
You’re Running Out of Time: The production of this song makes it my favorite out of your whole OST. The chopped production really gives the sense that we are close to being done and that there is a sense of urgency. I really admire how you are able to weave so many samples into your composition so seamlessly.
Quitting So Soon?: This sounds like a N64 Pilot Wings song and just hits differently. I like the polyrhythm of the 3 over 4 and think that this helps glue this piece together with the others using the theme.
Overall: This eclectic OST surprised me at every corner and in the end I am extremely impressed with what you were able to produce. I wish you the best of luck continuing your game project! Great work and thank you for sharing!
