Hey, maybe anyone can help me, too. Some time ago i played a flash game but forgot about the name.
One controls an archer to defend a tower in the lower middle of each map. Aiming with mouse, moving with arrow keys (bird's eye view). I think I remember Goblins to be the first enemies. The story was something about a boy defending a sacred place (tower in the lower middle) and one could gain exp. points and abilities (like summon a wolf or a hail of arrows around the hero) and buy equipment. Every forth or fifth level/map there was a special boss.
I think (and hope) that's about enough info for someone to recognise the game and help me!
