Isithiyo Challenge is a timed obby running game. The 16 people with the fastest times advance to Round 2, where there will be Double Elimination Brackets. 4 people will be in each bracket where only 2 advance. Round 3 is F8, and Round 4 is the finale with the final 4!
If you enjoyed Isithiyo Challenge, you'll probably love Sonic_DJzZ's One On Top! (OOT) If you'd like to compete in his, it is quite better and Isithiyo was heavily inspired.
