The opener really grabbed me! There's something wonderfully off-kilter about it. Definitely helped by that warbley organ sound, but it's also in the rhythmic feel. Really interesting compositional style, I dig it a lot.
The bass on Lousy Ol Town is goin' for it! Super fun to listen to. Your use of different time signatures is really enjoyable, especially feeling that on track 3. I agree with someone else in the comments that I got some Crash Bandicoot vibes from this and that's certainly no bad thing! The synthy bass sound that comes in towards the end of that track really pulls it together too.
The bonus track is a nice change of pace, but the style still fits the soundtrack. Honestly, I would've probably kept that in maybe made it track 3 (and track 3 would become track 4). Could easily be some music for a different area that is slightly more foreboding. Would add to the story! The bouncy melodic bit over the top feels like it keeps it close enough in tone to the rest.
Really enjoyed this even though it's quite short! I agree that there could be some touching up with the mix and maybe some added expression or variation ok play style with some of the instruments, but the ideas and rhythms and feel are all super engaging to me. Very enjoyable.
