Liberal Democrat leader Tim Farron slammed the Prime Minister for "running away" from the debate on Wednesday evening.
May ruled out appearing on televised debates soon after calling the election.
In the debate, opposition Labour Party leader Jeremy Corbyn asked "where is Theresa May, what happened to her?" while clashing with Home Secretary Amber Rudd, who represented the ruling Conservative Party.
Mr Farron signed off with a pop at the PM, saying: 'She can't be bothered, so why should you?
Fresh from, er, watching last night's TV debate, the Prime Minister will be heading to the North East where the Conservatives will look to take a slice of traditional Labour heartlands.
She said: "It's as though he thinks it's some sort of game - a game of Monopoly perhaps where you ask the banker for the red money to pay electrics, the green money to buy the railways and the yellow money to buy the gasworks".
The Greens co-leader was praised for challenging Ms Rudd about why the United Kingdom is the second biggest arms dealer in the world, while Mr Robertson was commended for accusing Labour of "aping Ukip" on immigration.
"Amber Rudd is up next".

Under the pact, the United States committed to reducing its emissions by 26 to 28 percent from 2005 levels by 2025. Both President Barack Obama and former Vice President Al Gore championed the pact .
Although the remarks from viewers and other politicians was expected, what we didn't think we'd see is a United States television show involving themselves in the drama, with many being left amused when the official Twitter account for Netflix's political drama House of Cards trolling the Prime Minister.
And Plaid Cymru leader Leanne Wood said of the Prime Minister: "She won't turn up to these debates because her campaign of soundbites is falling apart". She repeatedly accused Mr Corbyn of believing in a "magic money tree" but the Labour leader won applause when he suggested she was unfamiliar with the reality of poverty.
An angry Mr Corbyn was then applauded when he immediately shot back: "Have you been to a food bank? Have you seen people sleeping around our stations?"
Ms Rudd said the central question in the election was who should negotiate with the European Union on behalf of Britain, Theresa May or Jeremy Corbyn.
Corbyn began by repeating his campaign motto, saying the election was about "whether we want a country for the many or just a few?"
She said: "We are going to live within our means".
It was all a bit of a waste of time, says The Independent.
Earlier on Wednesday, a polling projection by YouGov for The Times predicted a hung parliament after June 8th, with the Conservatives losing 20 seats and Labour gaining nearly 30.
