This is really beautiful, the game truly has an identity of its own, this must have been lots of work for a single person! The sound design is well polished as well, even though the music may seem a bit repetitive.
Also the game feels interactive, special mention to the NPCs and sidequests that you managed to fit in. The varying speed of the swan was a bit off putting to me, but that's my taste.
The settings feel pro, first time that I see a jam submission with colorblind options. Props to the keybind settings, toi-même tu sais. One slight remark on these: there is no back/exit button, so you need find the one to restart the game, but as the settings carry over that's no big deal.
