I think the addition of new pieces was incredibly clever.

When I started playing, I first just tried to play like it was regular Tetris on the furthest side of the board -- a strategy that was quickly foiled.

The implementation of an extra dimension is also pretty cool, but as a game design nerd, I think it's more awesome that you managed to force players to engage with the concept.

Thanks! I was actually going to make an algorithm to find all the possible variations, but I realised that the additional options were limited and immediately obvious, and hard coding them would give me more control of game balance.

The blog is really about sharing ideas, so yes "forcing" the read is part of it XD - hopefully some ventured into the rest of the blog, which is more "saving the world" sort of material. I really appreciate your comments here, I wish I'd found them straight away :)
