Your feedback is incredibly useful! Thank you very much.
-Totally agree with art resolution, won't repeat that mistake again xD.
-Btw I did add coyote jump and it really made huge difference when I was testing it, I'm glad I added it. I might just slightly increase the timer in case the current time is not enough, I will look into that. Also agree on making it less punishing since some people mentioned they sometimes had a hard time with enemy collisions.
-I think that because my game over and win menus are Canvas Layers, they dont have this setting, so I'll try making them children of Control node to see if it helps.
-And I've just fixed my menu, It wasn't properly centered because I couldn't press left buttons of main menu, so I tried your advise and made my Center Container node a child of Control node and now everything is alighned and works! You're saint, thank you!
I'm happy to see such sweet and helpful people, it motivates so much.
