Quite a few years ago (probably 3-5 years ago) I played this game which I really liked. However now I have absolutely no idea what it was, can anyone help? It was a game where you have to protect a castle of some sort, at the start you pick between 3 (I think) types of 'warrior', a archer, a spear thrower, and I don't remember the third. Then you get attacked by waves of enemies, at the end of each wave you get to upgrade your character. Ringing any bells?
There are a lot of games that fit that criteria, could it be Stick War 1 or 2? Do you remember anything else, like what the characters look like? That would help a lot. You might just want to look through the Strategy games and see if you can find it there.
