If you have an '060 accellerator and a graphics card (Cybervision PPC, PicassoIV, etc..) the game is playable although there are some very minor screen lags on occasion. I have never attempted to run the game on an '040 with AGA only but I have read that gameplay is not really good due to severe lag. I suspect (opinion only) that play on ECS / OCS is not even a consideration.
Clickboom says that the minimum CPU is an '020 but I don't even want to think about that.
