The Bees blew a 2-0 lead at the Gtech to be pegged back and to draw 2-2.
Andrews said, "We are disappointed but equally we need to understand why I suppose. We created some opportunities and I felt like we could've had more if we had been a little more clinical and our decision making a bit sharper.
"Second half I wanted us to be front-foot and we couldn't get control of the game in the second half like in the first. We didn't do the basics as well and ultimately we're frustrated with that."
On Wolves' impressive form, the Bees manager also stated: "That's for them to discuss. I think where Wolves are it's pretty obvious they've upped their game.
"I think some of the players need to have a good look in the mirror as to why they found themselves where they are. There is a lot of talent in that squad. They can cause you serious problems. That's for Rob and other people to discuss."
On the team's hopes to the end of the season, Andrews concluded: "I think it's really simple. If we produce a second half performance again we will struggle, if we produce first-half performances of that level then we will have a good end to the season."
