Dude, you're not meant to post reviews of your own games on this database. But I'll let it go because this is a smart game, and you're a hero for making these games back in like 1991 and the writeup is quite interesting in terms of history.
Anyway thanks for liking my remake that I did in like 1999, even though it kind of sucked =(
Uh. I should write an actual review.
Well, there's not much to say, really. As far as games from 1991 go, the Smiley Guy games are the cream of the crop, so to speak (being previous winners of the superold ZZT's Revenge contest). The story is pretty simple- stop a mad doctor taking over the world- but I think this was the first game to frequently use objects as enemies (as opposed to like lions and crap), and the programming in general is a step ahead from a lot of games at the time.
The graphics are also awesome considering the lack of STK at the time, too. So is the music- the Toxic Terminator theme is still one of my favourite pieces in ZZT speaker sound (remember I used it on the stereo in Blue Moon?).
The whole thing is really good. If you've not played it, you ought to.
