Very fair point. I did think several times about simplifying and keep just the "pushing through oil part", since it felt the more fun for me. But felt that it was less original to have just that. Painting for me feel nice and satisfying, but sliding while painting felt a bit too annoying and punishing...but the game was about sliding so I was fucked and decided to keep everything :D
Thanks for the feedback! It's reassuring to see people having similar thoughts I had.
