I liked it, although before the portal i was considering not finishing the game because of the movement, but i did at last. The amosphere was actually spot on. The story was heart-warming at the end, nice touch that it was personal to you. Great music at the end :)
I understood the concept of this jam's seriousness criteria to mean how "childish" the game is actually, but I don't want to rate yours unfairly bc of that.
Feedback:
Options to adjust mouse sensitivity would be helpful, also brightness slider. The movement was really frustrating at times. It would've been better if the main focus wasn't on item placement and platforming on them with the current movement. Rather if the emphasis was more on platform rotation, which would've made the game fit more to the spin to win theme. There were too many texts sometimes.
