Butt
This was one of the first ZZT games I downloaded, and to tell you the truth I did like it to an extent.
I'm not going to spoil the plot for you, it's far too interesting to do that.
Graphics: Blokeware uses almost every colour available, and to tell you the truth it hurt my eyes on some boards because of the contrast. Then again, my eyes are a lot more light-sensitive then most peoples'.
Gameplay: Gameplay to this game is very simple, and annoying at some parts. I didn't like the invisisble maze, it reminded me to much of Tomb Radier: Pyramid of Power(shudder)
Blokeware uses a lot of humour, especially about devouring carcases and pieces of flab. i particularly don't like this type of humour, but I know a lot of other people do. I'm a more serious person myself.
The game also has one very big bug, Blokeware did not connect a board on a boss' room, thus you cannot possible advance without cheating/editing the game in advance of entering the board.
All in all this game is worth a download. But before you play it, you might want to reduce the brightness on your monitor. It helps.
