[PC][Early to mid 2000's] Top-down 8-bit game where you killed skeletons attacking your castle

**Platform(s):** PC, probably web-based, probably Flash

**Genre:** Top-down, 2d, point and click *or* tower defense, not sure which

**Estimated year of release:** Early to mid 2000's

**Graphics/art style:** Top down view of a castle. 8-bit graphics. Black background, grey castle

**Notable characters:** There were two types of skeletons that attacked the castle - wearing a blue shirt or a red shirt. The blue shirt skeletons were a different strength than the red shirt ones. I think blue shirts took two clicks to kill while red shirts needed only one?

I think there were other mobs that could attack as well, but I only remember the skeletons for sure.

**Notable gameplay mechanics:** Click attacking creatures to destroy them, possibly tower defense

**Other details:** This is almost certainly a Flash game. I remember a sound clip of "Defend your castle!"
