M-M-M-MATH!!!! oh noooooooo.
putting it all together took my brain out. like i had no idea what was going on. i had to research that stuff again. even then i couldnt figure it out. from what i gathered its ((x-2)^2+2)/2 , yet that isnt possible to make.
i gave up and started skipping through levels as math is not fun for me. the end credits are way too big and are unreadable as most text is off screen.
