Stuck in the ancient tomb?

[Taika]

I've gotten as far as the person in 2:55 of the Youtube vid linked below, he seems to push the lightning block towards the obstacle and it just opens up, for me that doesn't work - I killed the 2 lightning cube monsters in the previous room, could that be the cause?

That looks like a bug. Try using more cubes.
(edit: don't use the rod to get in; getting stuck will lose progress)

success, thanks for that!

@DeDGuY- @Taika if you get stuck just save and quit, it saves your progress while making you spawn again outside of the temple.
