Blackwell was delighted with his side's display but believes a lack of precision in the final third prevented them from adding to their tally.
He said: "We played some good stuff and looked as though we could score at will but then we got a bit sloppy. I think we should have scored five or six.
"It was outstanding and the fans are loving it. We know we're at the start of this and there are going to be some dips, but we're starting to find consistency in our performances.
"We want to make Bury a fortress and when people come here they know they are going to go back on that bus with nothing.
"If we win our home games and draw away, we're going to get promoted. It's as simple as that.
" We're building something that I want to be part of and, at the moment, the players are playing the way I want them to play. Hopefully we can keep it going.
"Cheltenham got to the play-offs last season but we've sent them back on the bus with a lot to think about."
Bury made a bad start as Andy Procter scored an own goal in the third minute, but they recovered with three goals in the space of eight minutes.
Danny Mayor claimed the first, letting rip with a 30-yard thunderbolt that found the top corner of the net in the ninth minute.
Procter made amends for his earlier slip-up be heading home Craig Jones' corner to give his side the lead in the 12th minute.
Then Nathan Cameron got on the end of a Jones cross in the 17th minute to make it 3-1. Substitute Jessy Reindorf completed the rout by heading home from Mayor's cross in the 76th minute.
