+ potion efficiency IS factored into enchantments. This is critical for squeezing in extra stats into enchantments and will end up providing more stats than spending the skill points into flat attack.
Suggestion - Show big numbers ($, exp) in scientific notation or with a prefix (K, M, B), as it is really hard to tell how much it is when it's a line of numbers
sry for double post, but you can get UNDER PAR for some levels, levels I got under par in are 19,21,29,31, not sure which other ones you can get under par... under par gives you a gold star btw
Level 9, remove the blue directly to the right of the green.
21, remove the blue facing down, then the one to the right of it, then the blue holding the red AND blue, the rest is self explanatory
