Hey hey thanks for playing and rating, glad you had a bit of fun :)
Tysm for the feedback, I do agree with you that it's a bit long (particularly for a jam game) and the difficulty spikes way too much in the middle. The Golden Yoyo actually moves around the screen twice as fast as the base yoyo, which is supposed to make the last bit of the game a bit harder (although you can now reach higher places). You're not the only one who didn't realise this though cuz it's only really communicated with some text above the Golden Yoyo before you pick it up.
For the post-jam build I'll be playing around with some ideas of what the Golden Yoyo could give the player because even if it was clearer that it's a speed "upgrade", that's a bit of a boring upgrade 😅
