Review by David Welbourn (originally posted at Baf's Guide)
A bizarre and frustrating game experience where you try to infiltrate the Silli Productions building in order to play, then destroy, the game known as Amissville. Amongst the misspellings, illogic, poorly described rooms, missing implied objects, insufficient number of synonyms, and a notable lack of player direction, there lurks a cunning puzzle or two — and several ways to die. To succeed, try anything and everything. Knowing how to deal with usenet trolls will help, too.
