ITSP is gonna be huge if people can get past its lack of instruction. there are no words anywhere in the game and the music is mostly just ambient whirrs. the controls are unusual for about five minutes until you realize what it's going for and then it makes sense. the lack of communication will make it difficult to demo, though.
that said, this is the most Metroid-y thing I've played since Super Metroid itself. moreso than Shadow Complex, moreso than Outland, moreso than any of those games. pure exploration and atmosphere. so good.
