Answer 1

I love this! I like the marked areas for where you have to hit the quill, but I think the trash bear should have had something similar. The timing is very weird, I would've liked a "Be there when quill is here" kinda marking. Maybe two lines like this ( https://imgur.com/a/SNRHZdf ) to show the player where he and the quill needs to be for the  bear to hit.
Will SS soon, when I get the timing on the bear and the boost on top.
