Ok, here is another cool flash game: “Auditorium”. It is a puzzle game with a twist, divert a flow of particle around the playing area with different tools trying to reach goals. It’s hard to describe, have a look for yourself: http://www.playauditorium.com/
I stumbled across a cool text adventure today (it was mentioned on a mailing list a work). Even if you have never played a text adventure before, you should really have a look at it. It’s really good, kind of mind bending at times.
I just found an interesting flash game called “Fantastic Contraption”. It’s kind of like that old game “The incredible machine” just with less exotic parts. Actually I like this flash game better since there is no “right” solution, there are endless possibilities to solve the problems. Unfortunately that doesn’t make things easier 😉 Have a look for yourself:
