It needs a little bit of work on physics, but mostly ON SCREEN SIZE with my mac M1 it's a small screen if I wait too much at the end of the level I can't even see and click on the 'next level button'. On the menu the start button is half cut by the screen. (Maybe your lucky day I think I know where your problem is ! Just go to your canvas objects in unity and use the 'scale with screensize option' It should be much better !) Great job for the game !
