What an experience! The story was really meaningful and I really enjoyed what you did with the limitation, haven't seen anything similar in the jam yet!
Some personal suggestions for the gameplay, if you don't mind! You may want to include the "platformer shadow" or a form of it so that it's clearer where the player will be landing. The parts with the ceilings were also quite challenging but still doable. The dialogue was meaningful but I'd suggest that you have more consistent Capitalization and Punctuation, it's something I learnt in my game dev classes and it does really add to the polish of the final product! Hope the feedback helps a little.
I had a great time with the game and I made it to the very end :)
Keep up the great work!!
