I enjoyed it up til the symbols. I couldn't get past the first. "Symbols" is too vague. What kind of symbols? ASCII Peruvian? too broad a category.
I also think letters and number should be broken up.
Finally, when you change types, or actually for each type, you should say underneath what it is you are looking for. I was still thinking shape, when I should have been thinking letters and numbers.
Overall, I liked it.....til the unfortunate symbols bit.
Pretty good, though as stated, more than one axe hit would be good.
Also, minor bug, walking over the spot where the coin was repeatedly you can pick
up multiple coins, though the coin is no longer there. I was able to get six pickups
from one coin, though I don't think the coins get you anything at this point.
