"Though, on the balance of play we definitely deserved the points. We looked as if we could score every time we attacked, but our problem of late has been that lack of a ruthless edge in the oppositions area.
Levy's spot-kick added to earlier strikes from Josh Bharier and Kyle Bentwood.
Kristall added: "It is nice to win three games in a row. This season and in the league particular, we have lacked consistency so this is a good time to be picking up wins.
"All of these games are very useful preparation for the Cyril Anekstein Cup final in a fortnight. We are getting our players minutes and that is vital to ensure we are match-sharp for the Hendon test.
But before the final Oakwood must play double-chasing HMH in the league. "We now focus on a big game at the Hive on Sunday where we will look to get as many players minutes as possible," commented Kristall.
"We have been very unlucky in our games with HMH so far this season and will be hoping to set the record straight this week.
"They also have a big final to prepare for and with the title race over for both sides, I am sure we will both have the same mindset.
"Overall, this was a good game - end to end where both teams had nothing to lose. In reality, it felt bit like an end of season game."
