Striker Mo Eisa admitted the introduction of striking duo Brian Graham and Elijah Adebayo helped change the game as his 14th goal of the season secured a point against Barnet.
Eisa superbly volleyed home a cushioned header from Adebayo in the second half as the Robins fought back at the LCI Rail Stadium.
"We didn't start well and weren't at it in the first 20 minutes," admitted Eisa. "They came at us and we didn't play as we wanted.
"The second half we changed it, brought Brian (Graham) and Elijah (Adebayo) on and they changed the game. We went more attacking and we had better quality.
"We had three up top and it caused more havoc for their centre backs. Getting a point is not what we wanted but we take it.
"When teams sit in it is hard and you have to break them down. They are fighting to stay in the league."
Eisa has now netted 14 times this season but insisted after the game that he is happy to keep on learning at Cheltenham in his first season in full-time football.
"I have got to keep working hard and for the team," he said.
"I am happy here, I am learning and I am trying to improve my game. The gaffer gave me a chance here and I am so happy for that.
"You learn evry game and there are games when it doesn't go as well and you look back and see what you could do differently.
"I am leaning here, it is still my first season and I am happy with that."
