McInnes was speaking after his side moved to within a point of Celtic at the top of the Premiership with a stirring comeback against Partick Thistle at Firhill.
The Dons went a goal down when Jags midfielder Steven Lawless scored a wonder goal on the hour mark.
But the introduction of Barry Robson changed the game, and two headers in two minutes from Andrew Considine and Simon Church brought the Dons title hopes back to life.
The Dons have now lost just one game in the last 16 in the Premiership – that sole defeat a Willie Collum-influenced visit to the Highlands – with four games left until the split.
McInnes said: "There is a good wee bit of momentum, it is just important that we try to keep dragging performances out of the team.
"I think there will be more games like tonight before the end of the season but I am loving it to be honest.
"It will be a rollercoaster, there will be games fraught with nerves for everybody else.
"I thought there was a lot of tension from the supporters tonight but thankfully the players never showed that, they kept being confident and backing themselves and it is important that they keep showing that.
"The players showed real determination. It was a big ask for the players to get that result and they had to dig deep, they deserve so much credit.
"It would have been questioned; character and bottle and all that stuff.
"We lacked a wee bit of quality and thought at times but the determination and character was there as you saw with the result.
"I was proud of the performance tonight, that is why I love working with these boys, they never know when they are beat."
