Really great concept, I got stuck in the part where there's a big gap between you and door. It may be my fault but I don't think jumping can make it that far.
Only part I didn't like is you have press buttons via mouse. I wish I could reind the buttons that I put to A and D keys. I'm looking for after-jam version, I think your idea is unique. You may want to expand it to mobile game or something. Have a great day!
