Updates on the original include:
- Homing blocks. While parts of the playing area could move in the original, in the update there are also certain blocks which home in on you, and - unlike you - are not stopped by walls!
- Invisibility. Usually a bonus in most games, this is a crippling power-up. It is invariably placed so it is impossible to avoid, and means that your cursor vanishes.
- Gold keys. These unlock sections of the current level, and are simply a game mechanic which forces the player a certain way, without the use of walls.
- Black keys. These are fun, and despite the fact they should make things easier, they don't unless you think about it!
The game comes with a handy timer, and it took me 1261.13 seconds to finish the whole thing. Literally about half of that time was spent on level 25, so if you do that one quickly you should comfortably beat my time.
In terms of ease of play compared to the first game, it's quite a lot longer. The first game took me about half as long to complete in one sitting. I really enjoyed it though, despite its occasional roar-inducing frustrations! The moment I reached level 26 was a happy one. :)
