A very simple XP system for any game that needs it. I haven't actually seen any games on scratch that use XP, but there must be a few that could make use of it. Also it quite interesting to make. Growth curve: XP to next rank = 50 + Rank^1.4 50 is the 'base' amount. You can freely change it to whatever. 1.4 is a measure of how much the 'XP to next rank' variable grows. Less is slower (easier) and more is faster (harder). The exponent is made by: 10^(log(Rank)*1.4 Press and hold space button to award XP.
