So, I haven't played Celeste yet, but I will correct that sooner or later.
So naturally the start had me kinda stumped for 10 minutes. Unsurprising, considering this is meant to be played after Celeste, not before. Guess it's been too long since I last played a 3d mario game. I personally found this hilarious, but not everyone takes delight in repeated failure. I appreciate how silly the secret signs are.
These two cassette strawberries are the only ones I can't get. Skill issue, really.
(I had an image but it was too big. The cassettes I refer to are the one under the credits and the one on the block attached to one end of the floating road. Walljumps ain't my best skill.)
Also, Madeline struggles to jump straight (because she isn't eyyyy) when walljumping off the meeting point of two separate blocks. This was most noticeable in the walljump strip of the central tower. The meeting point often led to me careening of to the side into oblivion.
