Wow, that was funky as hell!
Just like you described, these tracks would fit perfectly in a gacha game of sorts, and would fit the each particular situations as well.
Very fun playing, much like others said 'FIRST ENCOUNTER' goes incredibly hard, but even the other tracks have very polished elements which come from the great production you made.
This really is game-ready, could easily see this being played in an actual game!
Great work!
