I was part of a team that just submitted a platformer named "Spacial Delivery" to another jam just now, and I happened to search and was curious about all the others named that out there haha. This is fantastic, especially for your first game. I love how the music changes pitch based on what setting you have (though I would've more intuitively gone lowest to highest gravity from left to right as opposed to the other way around). The mechanics are there and solid, and I honestly had a blast. Great job!
