I love the vibes here! Fun music, fun art, some really nice juiceness to movement and the UI - impressive!
That said I agree with other folks that I found the start way too challenging. The package retrieval mechanic is pretty punishing and I found it I made a mistake it was easy to get stuck in a loop trying to recover the package and then hitting an obstacle immediately, which I found a little frustrating. I got stuck in the well a couple of times.
I think it'd be nice if the difficulty had ramped a little more gradually so that I had a bit more of a feel for the movement - I bet I could have dealt with my problems in the well with a little more practice.
Really nice one though! Feels very complete, impressive that you made it in a week.
