The pint-sized 18-year-old forward scored two goals to help New Zealand seal a dramatic 4-3 overtime win over Greece in its third division world championship game.
"It was an amazing feeling," Eaden said.
"The guys really pulled it together in the end. We had them on the back foot the whole game and it was just a matter of time before we got the puck in the net."
With three minutes remaining in regular time and New Zealand trailing 3-2, Eaden scored from a goal-mouth scramble to send the game into overtime.
The match-winner, a golden goal one minute into overtime, was a superbly executed shot under intense pressure.
With just Greek goalie Ntalimpor Ploutsis to beat, Eaden went left and lured the keeper wide, then slotted the puck past him.
Ploutsis had been outstanding all night, pulling off some remarkable saves. So Eaden's move showed plenty of courage and underlined his class.
"It still feels unreal at this point in time. I was completely stunned when it happened and didn't believe it. I needed a second look."
At 1.62m tall and a paltry 71kg, Eaden hardly cuts an imposing physical presence.
In a game where padded-gladiators glide gracefully across the ice before crashing into each other with extreme prejudice, he has to get by on speed, agility and the rare knack of showing up in the right spot at the right time.
"You don't need to be big but you've got to be quick.
"I think the worst bumps and bruises I've got from this tournament was at the end when everyone was jumping on me after I scored."
The pads help and most of his injuries have been muscle strains, although he did fracture his pelvis last year.
Eaden took to the ice as an 8-year-old after badgering his mother until she eventually relented. His inspiration was the 1994 movie D2: The Mighty Ducks.
"I videotaped it and watched it just about every single day for a good few months, and Mum just gave in and said I could give it a try."
Eaden helped the New Zealand under-20 side win the third division world championships in Serbia and was named the tournament's outstanding forward.
He is in his third season with Canterbury side the Red Devils. They were beaten by the Botany Swamp in the National Ice Hockey League final last year.
New Zealand's final match is against Ireland tomorrow night. The Irish were beaten 7-4 by Greece and 8-3 by Luxembourg.
