The first thing I noticed was the UI sound for clicking buttons just pierced my left ear. I did not like that :) Just a small issue though!
I really liked the intro, it perhaps could've used some sfx with the appearing letters as that is expected nowadays. The gameplay was alright, no more no less, the jumps felt a bit off with the strong gravity back down afterwards. However the details of the sprites, the background/ambience and the little animations were really cute and polished!
After reaching the end I thought that maybe there is some way to get more points, but I couldn't restart the game, it just loaded the ending scene instead of the level.
The theme of the game jam felt a little forced. Perhaps with a few more levels that slowly answer the intro questions (What am I, am I an alien, etc.) this could've been integrated a bit better into the game.
The polish makes this a really solid small game nonetheless!
