It took me a while to understand/solve the second gravity puzzle but once I did then I got it overall and was able to play to the end (there's a bit of a lie there - damage was done because my files are gone!). I had to keep taking screenshots because I kept forgetting the syntax in the beginning so it would have been nice if the notes had stayed in the notepad.
It was a clever use of physics - I was messing around with gravity and speed and making the circle arc upwards and downwards. It felt like I was playing golf at one point.
There seemed to be a bug in that at times I made the walls solid but the circle still ended up going through them (I can't remember the exact conditions but it might have been when the speed was quite high).
(I just noticed there are some clues in your screenshots. I didn't even see them until I was typing this comment now.)
I don't know how I feel about how this connects to the theme - I feel that in real life it would be easier. There were some moments where I nearly gave up and was very frustrated but personal stubbornness made me push through, although it wasn't a great feeling. There's an interesting balance between things being just right and a little too hard but I realise that's very difficult to finesse for a jam game. I did like that there are multiple solutions to some of the later puzzles and it's whatever creativity the player comes up with and which works with how their brain works, combining both the physics and the coding.
I really loved the art and the UI.
I'm torn between thinking this was almost the perfect length (there were maybe one or two too many levels) and it being a great prototype for a larger game. Well done though.
