Engine revs car doesn't accelerate just replaced clutch

Question

just got it clutch and slave cylinder replaced today car drove fine for little while then engine started reving without accelerating it still drives but i have to baby it

Answer 1

does it move at all???

if it moves, sounds like you don't have the  clutch

adjusted right or didn't bleed the clutch

Answer 2

sounds like the clutch is slipping. if it will not hold under power, that is all that it can be. it ts possible that you have a pedal free play problem. i would go back and have that checked out.
