how are u aable to kill the bosses in the alloted amount of time and stil take that long?[/quote]
you can stay in every boss stage for 3 minutes max (you get kicked out at like 2min 59 seconds or so) and some dojo buffs in resting spots add 1 minute to your total time.
considering there's 40 stages (3 min x 40 = 120 min) and 7 resting spots (1 min x 7 = 7 min), you can theoretically get a 2 hours and 7 minutes time, or at least over 2 hours for sure. I decided to cut it at 01:33:37 for lols' sake
