press spacebar to throw the ball, the arrow is meant to represent how far you are to the centre as well as how high you are going. this is for my school work this is working alright the problem is that when it says its touching the sprite and the colour it only shows 10 or 15 points which is why i had to darken or change some of the colours. another problem was rounding the set score (which is the score you should aim to get (no higher or lower)) and even when looking it up i had trouble finding things out but i was able to figure it out. feel free to use this for a base but please credit me for the original code!
