this is such a cool vibe! the first two tracks feel like they'd be in some rpgmaker puzzle game (i might just be thinking of oneshot). the synths used remind me of celeste.
i will say that the third track sounded a little weird once you started bringing in melodic material other than the main motif -- maybe try focusing on making the climax more slow and grand and less boss-fight ish? it kinda feels like a departure from what the first two songs were doing.
that's just me tho. i'm not really an expert at composition so feel free to disregard what i just said. i really like your submission overall, good job!
