New problem with satsuma doesn’t move well

Okay, managed to get everything working(engine) starts nice and idles smooth,

I put it into gear and go to drive, it’s moves a little but it’s like the handbrake is on (is down) I have however noticed that the drivers side front wheel (tyre) is in the ground slightly and the front ends is dipping down to ones side, so I’m guessing that the strut might be damaged but how would I know if that’s the case? If it’s not damaged is there a possibility the tyre is flat?
