I wish I had this game as a kid, I would have loved it. The games music is awesome. The world is huge and filled to the brim with content. The play varies, from having to move in one direction, to reading a map, to dodging conveyors, to outrunning the screen, and probably more. But I wouldnt know, I didnt make it that far. I took down notes, made my way through the hall, chapel, and tower, expecting some final outcome, an explanation of the plot, an ending, but this turned out to be just another gem. I dont know what to do or were to go. Another reviewer mentioned a hell, and there is room on the map for it, but I dont know how to get there. The only thing I can think of is getting all the gems, but I skipped several as the game told me they unlocked a secret, not that they were critical to completing the game. If im right that you need all 30 to beat the main game you should really consider updating the games text to reflect that. It stinks to make it this far and realize I need to basically start over to win. If im wrong consider putting someone at the bottom of the tower to give a hint on how to beat the game. I think it would really help.
TLDR: The game should have clearer instructions but besides that it is amazing!
