Thank you so much for all the feedback.
I ran out of time to add sound and/or music mainly because I've never done them before in any game. I didn't want to try to learn with one day left in the game jam and still have a lot else I needed to do. I honestly had a feeling skipping the tutorial would be a major problem and I do agree that without sound it's kind of hard to tell when things are flipped.
I also did not have time to add coyote time or the other things you mentioned. The ramp physics were definitely bad. I honestly didn't like where the game was going for the last half of it but I was already so far and I just wanted to finish it and make it playable.
Thank you so much for the feedback and I will try to do better on my next jam to make a better game for you guys.
