Combo Pattern Drawing Rework!

The old combo drawing system was too complex, especially for first-time players. So I changed the system to where you can perform combos using only one finger instead of 2 in the old system. This should hopefully make it a lot easier! The new system works by drawing the combo pattern then letting go and then clicking anywhere on the pattern to activate it. Or if you don't want to do that attack you can click anywhere else but the pattern to reset.

Because that changed I also reworked the tutorial slightly and fixed the spelling mistakes in it too.

Also nerved the AI again for easy mode to make the experience for first-time players even more!
