Congratulations on making your first game, that's a real achievement and it's a complete experience in that you have a tutorial, main loop, ending, animations, sound effects, music and it all tied in well together.
I play very few platformers so take frankly everything I have to say with a pinch of salt. I liked the way the tutorial was presented, I did however find they some bits of information maybe came after the fact. For example, there was a gap which I double jumped across / up to, before the double jump tutorial was visible. I'm not sure if it was possible with a single jump, but I would have maybe liked that to have been shown a little earlier.
I liked the spinning / wall riding mechanic greatly. I think it thematically makes sense that as we are spinning or rolling there's quite a lot of inertia, but I did slide into spikes quite often, maybe that's completely intended haha. The camera had a little kinda vibration for me, it wasn't a problem for the the length of game here, but I can imagine for a longer game it might strain my eyes a bit.
I thought the game was an excellent length and I liked the difficulty, nothing ever felt too easy nor difficult and it didn't outstay its welcome.
Thank you, and very well done for completing your first game and jam!
