Last Flashgame I played was VectorTD... a remake of the oltimes favourite Tower Defense It's a great way to waste time. And had I know the following about a few hours later it would have saved my workday...that was absolutely uneventfull - to say the least
But anyhow. Carter gave me that link to Epsilon. Great entertainment and funny little game of portal like thinking for the poor. But a lot of fun and easy riddling non the less.
Give it a try and tell me if you like it. Do you have other games you like? Tell me as well...
