Here are a few great Flash games that have held my interest for more than a few minutes. Most links came from Game|Life (thanks Chris).
- Winterbells – Very simple but well build game. Kind of a variant on the kick-up type games.
- Flash Element TD – A Flash game based on a mod of Warcraft III? It’s a simple but addictive strategy game.
- Four Second Firestorm – A WarioWare clone created by several different development teams. Very fun but I don’t know who still wants listen to that Eurotrash Club music.
