The Shaymen suffered their 15th away loss of the season at Stonebridge Road on Tuesday night, and must now make the most of their games in hand if they are to avoid relegation from the Nationwide Conference.
Wilder told the Halifax Courier: "It is not all over but we have made it difficult for ourselves.
"I will be looking at the players in the next few days to see who is up for the battle."
Wilder believes that all is not lost and it is down to the players to put in the effort if they are going to avoid the dreaded drop.
He added: "We still have seven games to do it and will have opportunities to do it. We have to make sure we give it a real go and get back on an upward curve."
