* As far as I know, the only timer problem in Space Quest 5 is the EVA scene were you need to rescue Cliffy with the pod. The controls are very hard to handle because the ship moves too fast. Normally, this puzzle is already very hard. Not only is it already fast, but you have little fuel. This puzzle requires some mouse skills, so don't whine if it doesn't work right from the start.
* I've spotted some small animation problems, most notably the GradeMaster 2000 sequence. Maybe some scrolling screens effects are eliminated by timer problems, but so far I haven't found any.
