Aperture Tag: The Paint Gun Testing Initiative reviews

the paint gun idea seems fun at first, but it got boring fast. i found the puzzles kinda meh. the jokes aren't really funny and it has the stories mel performance problem
The main reason why I give this a 'meh' is that it costs actual money while the much better Portal Stories: Mel (and many other mods/community test chambers) are absolutely free. It's not BAD, it's just less fun and has way less content than Mel, and Nigel is no Wheatley or Virgil. 
An interesting take on portal based puzzles, one worth playing.
