Cleared in 5 minutes and 4 seconds, sadly beating my old time with Viola. Also, my capture card sucks, as you may be able to see. It also has a very slight delay, so I couldn't react to certain obvious highs and lows. So this could've been even quicker in fact... even more so if i were allowed ring outs.
This video was made to prove my side of a little debate. The rules were no ring outs and to complete it without losing a round.
Specifically, the point is that 6B+K almost always hits. You cannot play Viola normally without 6B+K, ergo, you cannot play Viola normally without exploiting the AI.
Yeah, CPUs really understand Viola, don't they? I'll let you decide, DEX. ^^
