I really appreciate a progressive beat... Less common in the OST jams and yet very frequent in actual videogame soundtracks. I would chill on my Thursday night with these tunes - they definitely give a sense of isolation and the sounds of the waves are blended in well. I love the theme of your hypothetical game... I'd play it just for that. (Probably because that's been a running theme for 2022 for me, resisting denial, radically accepting, moving forward, etc.1)
"Dream of the Moon" is my favorite for it's solid bass riffing. There is something about the electric sound of "Something is Changing Within Me" that seems to not match the others. If I new sound/music a little better, I'd probably have a more helpful adjective -- too chirpy and square wave? Like you said -- they're good pieces that stand alone more than usual for you. It's a good piece that stands alone.
Great work!
