Hi, now that you make think about it, it is really similar to that part from Celeste, and I take it as a huge compliment. On the ball part, when you press space, a down force is applied to the ball, and you have to "surf" the slopes in order to reach the blue energy ball that went high up at the beginning of the section. On the game's description there are some other tips if you want to try it again. Unfortunately I had no time left to polish that part as I wanted, as I had to upload the game in time for the jam. I hope you can get past that part, it gets really intense at the end!
I'm glad you enjoyed the game overall, thank you for the feedback <33
