This game is difficult. It only spans a handful of rooms but the sheer number of objects that need to be manipulated into other forms (sometimes more than once) is very large. In fact, probably the most I've ever come across in a single effort. There are also some timed sequences. One annoyance is that parser responses to player input only stay on screen for a few seconds. I ended up using the F9 key in Altirra a lot to pause game play and take screen shots. Unparsed player input is not recognised as such; the screen merely refreshes with no response. Having said that it is an interesting game.
