Adam's Venture Episode 1: the search for the lost garden

Could anyone help please. I have got as far as trying to light the 4 braziers, I tried it about 3 times and got the gate to lift but couldn't make it to the gate in time. I then had to leave the game and I have been back several times since and have been unable to do it. I have tried filling the place with smoke (approx 5 mins) but the gate didn't lift. I haven't seen it lift since the first day. I tried timing how long the braziers stay lit and the one on the left only stays lit for one second. Can anyone help. Thanks

This is what the wt states:
Light the fire stands and note which one stays lit longest or shortest time.

Run (shift + arrow) to light the fire stands. I just kept running and lighting the fire stands until smoke filled the cavern and the gate rose.

This is what Pollo Diablo states:
For me the best route was to light the second from the left first, then the rightmost, then the third from the left and finally the leftmost. But you may find another route easier, for instance 2,3,1,4. When the gate opens, pick up the missing block and return to the white stone ledge.

Thank you. I had tried that but I only had 1 second and it didn't give me time to get anywhere. I was hoping it is a fault and there might be a patch or something.

I don't have saves to help you since this game is by checkpoints.

Thanks for the help anyway. Myrtle
