This was one of the most frustrating games I ever played. Not because of the hard platforming but because of some of the FUCK YOU moments, like the sign after the section where you get the speed upgrade. It is hard to get there and I died and had to do the section all over again just to read a little congrats message.
Other offenders like this are some of the pits you can jump down to find yourself back down at a earlier platforming segment that you now have to repeat just because you fell down into a checkpoint.
And as far as I know, the corridor with the sawblades that go up and down is just completely useless. WHY ?
Some of the platforming is a bit too tight and goes on for too long but its not a big deal.
Overall a worthwhile experience and I especially loved the art and music. Also the switch power up, while not very original, is awesome and I wish you would have done more with it.
8/10 -you really FEEL like batman.
