Very good, but too similar too lemmings.
I don't deny I like lemmings, fantastic game.
But if I wanted to play lemmings, I'd play lemmings.
Bug in the "nuke" script. If you have a builder, and you nuke, the builder won't die, and the gamebecomes locked (you can't do anything, you have to quit and start from level 1).
I'd call that a pretty big bug.
Anyway, nice graphics, but I can't give you 10/10 until you put a big Psygnosis logo on the menu. [Psygnosis made lemmings]
I would rate it higher if you didn't have all the same tools, example: instead of a blocker (who ever heard of a student being a blocker?) why not make the student throw up, so all the other students turn around because they are not going near the vomiting one.
See? It's probably enough to stop me thinking "lemmings" the moment I start.
