has anyone played the simpsons saw games! help

[Zepondrax]

So I found the Simpsons saw games on the internet across multiple websites. they look interesting so gave them a go. I get the talking parts in the Bart one and the homer one but once that is done the characters wont move at all? I read the instructions which say the ground is clickable to move the characters, but whenever I try to click the ground or click the character (Bart, Homer) they won't move at all. I tried arrow keys etc and nothing. Multiple sites I cant get it to work on my desktop pc?

I watched youtube and seen others get it to work so why are these games not working for me? I tried a different browser too in case it was a browser issue and not working, They load up but the characters wont move when directed. Anyone get these to work at all?.
