Nice one, Iove this kind of atmosphere. Huge architectural structures set in ethereal worlds. The platforming while being simple was smooth. The robot was really cute with those little wings opening when jumping. The sound design was great too, with some nice Carpenter vibes on the music.
PS : a few month ago I released a game with some similar themes/visuals, it's on my profile (Essence//Structure), maybe we share some references in common so it could be cool to chat somedays :)
