The overall aesthetic of the game is fantastic - I loved the pixel art and the animations! The sound design and music was also really good. I also really enjoyed the story - I was quite invested in it and am really happy that you provided the ending video on your page.
It's unfortunate that there were game-breaking bugs, as the game play was great and the controls were solid - I had no major problems with the gameplay itself. The only issue for me was that it was not clear to me right away that I could fall in huge gaps - however that's minor as it was mostly a lack of understanding on my end.
Overall: great job! This was definitely one of my favorites among the submissions I've tried thus far. I don't know if you plan to continue this further, as there is definitely potential for interesting game play ideas after this game's ending. I won't mention them here to prevent spoiling, so hmu on Discord if you would like my suggestions on that.
