XaeL, you're obviously really good at Tetris, yes it's similar, but for me having to rotate both the piece and the wall flumoxes me. I still haven't got past level 4!
Yes, you're right it looks the same, but it plays differently. I think that's where I'm being scuppered, it's the ability to rotate objects in space. In Tetris you are rotating your block and looking for where it goes, here you're rotating your block AND rotating your wall.
