Having a different power at each turn is interesting. However, the pace of the game prevent to really enjoy it. Each level are pretty long, and randomly generated, thus you don't really see the differences between them. In the end it's always a procedural map. As for powers, I got teleport several time, thus the game was mostly the same all the way. Also I feel like even the smallest size of the world can be pretty big? I spent most of the time running around randomly, hoping to find a crystal, which isn't much exciting.
The procedural exploration concept is good though. It might lack an additional mechanic to avoid making it repetitive, and really enhance the random generation aspect. There are cool ideas, I like the dice roll at the beginning of each level, and the 1 minute limit for each one (though I wish it would be less punitive, having to start the whole game if I don't find the crystal prevented me to go really far). Maybe there could be a way to make the dices more meaningful. If I get a "6", I don't really know what to expect at all. It could be symbols instead, or clues, or special rules. Overall the game is a nice prototype that can expand in many ways. Good job for that realization!
