Lol, delapidated...
Well, the idea is nice and all, learning "moderately common" words, but it's somehow lost due to the fact that you can try any answer as many times as you want to, with no penalty whatsoever.
On the other hand, the pyro-tracking part is quite annoying since you have, let's see... 3+2+3+2+4 = a lot of chances to screw up along the way.
The game is too straightforward, you can, at any given moment, do exactly one thing, despite other options. Maybe you should work on gathering more clues or the game should have different endings depending on how you played it.
Graphics were simple, but it wasn't so bothersome since it's not what the game is about. Music was good at least, despite the one recurring song.
And it's spelled dilapidated, with an "i". Grammar police on strike?
