Trick to beat the first Batcycle level
The first time you use the batcycle with Batgirl, you will have to keep driving until you reach Poison Ivy's garden. There is a glitch that if you press Select, it will automatically bring you to her garden and save you a lot of time, possibly some extra lives.
