IN SHORT: Mario Bros. Speed is a good level for the INTERMEDIATE player. It gives challenges, especially if you're going full speed. Crashing into walls is extremely hard to avoid at full speed. The level is definitely worth a go, but it might take some tries to get it right. It can be finished in about 0:37 at best, or 0:35 with a glitch. Edited by Daggarn, A.K.A 898ppp
