click of press space to jump! When you click the flag it resets the fact that you completed the level and that you have your cats. If you change your cat when you have one already bought you have to buy it again after you love and heart and unlock level 3 and you click the green flag it locks it again. So just touch the heart and star, don't click it, and it will unlock again.
Thank you to @TimMcCool for the heart and star detector! Thank you to @Footcheese58 for inspiration! All other code is me!
