I liked parts of the game, and didn't like other parts. I'd have to say that I usually find upgrades in flash games unbalanced. Either they're aren't enough, or they take too much grinding, or any other number of problems. It's very hard to find that balance. Bowmaster does actually have an okay balance, but there are a million and a half upgrades, and it takes way too long to buy things. So, while I appreciate that the upgrades have a lot of depth, it didn't pan out very well in the end.

Putting aside the references to Robin Hood, your goal is to compete against various archers in a competition to score the most points in an artificially created shooting range."
