this is not really an advice seeking post but more like a vent/rant (spoilered just in case)
5c is quite literally on the verge of making me just straight up delete the game. i spent the better part of an HOUR trying to beat room 1 and then got past room 2 with relative ease. i literally cant even get past the first 1/3 of room 3. the corner boost coming out of the red bubble that you take down-right is genuinely impossible for me. ive beaten all the c-sides leading up to 5c and i have never wanted to throw my controller at a wall more than playing that section over and over again. its insane because NONE OF THEM made me this tilted UNTIL i got to 5c. its so extremely discouraging and makes me want to just outright quit. im not expecting anyone to see this or even really care i just kind of wanted to shout into the void so i dont cry and break something.
