The Tottenham player made his first-team debut after joining the npower League Two club in September and has been a regular throughout the campaign.
The 19-year-old feels exposure to the realities of top-team football has hardened him and he even had to deal with an on-field incident which led to a Gillingham fan being charged with assaulting him.
Archer, who is in line to start when Billy Stark's side host Luxembourg at St Mirren Park on Monday, said: "I have played 30 games there now so that has been good for my development.
"As a young keeper, playing games is the most important thing.
"Jack Butland is the only other 19-year-old playing in the Football League so getting games of that quality at this age is good.
"In league football, everyone is playing for their future. The pressure of going out and getting three points every week is different. That transition has really helped.
"Playing reserve-team football for Spurs is good but there is more importance added to every game in the Football League.
"There are added pressures and more fans and I have enjoyed every game."
