Manager Graham Coughlan was left feeling disappointed after his side fell to a 4-1 defeat at Bradford City on Saturday afternoon.
Goals from Callum Kavanagh, Andy Cook, Bobby Pointon and Jamie Walker were enough to condemn the Exiles to an eighth straight defeat in West Yorkshire.
The result means that County finish 18th in Sky Bet League Two.
"It’s not been good the last eight games, it’s not been acceptable," said Coughlan.
"It’s probably a little bit of relief that the season’s over, it’s just been too many games for us with too little players, too small a squad to try and compete for 57 games.
"It’s almost become like we’re running in treacle every game. We’ve demanded a lot off them [the players] and we’ve got a lot off of them and if the season finished in mid-March, we would have been relatively happy, but it didn’t and it was just too many games for us, we’ve just run out of steam.
“For the first half an hour we were really good. I don’t see that as a 4-1 game but we have been getting punished.
“Let’s get it straight, the first two goals that we conceded were inexcusable. With 44 minutes on the clock we just needed to turn the ball in midfield, put it in behind, and lock them in to see it through to half-time 0-0.
“Instead we came in 2-0 down after two free headers six yards out. That’s something that needs to be cut out and sorted if we are to take play-offs and promotions seriously next season.
“I was really annoyed with the players because I thought that they were the better team for 44 minutes.
“Our game plan was spot-on and everything about it was really good, then we had two mad, crazy moments and came in at 2-0 down with the game effectively over.
"I’ve asked a lot of the lads, some of them just couldn’t maintain it. We ran out of legs; we ran out of bodies. Injuries hurt us; I get all that but the first half an hour I thought we were really good.”
He added: "I probably started building for next season as soon as our play-off hopes evaporated. We have a lot of work ahead of us, we can’t accept what we’ve had as a football club over the past eight games.
"I get most of the season we’ve been very good, we’ve been competitive. The injury windows we’ve had has really hurt us, so we have to learn from that and put together a bigger, better and stronger squad for next season.”
