Not a massive change but....

Reviewed By: MathUser2929 on 07 Jun 2016

The level graphics are largely the same as the original game, but the level designs are all new. I recommend trying this out and seeing if you can beat the challenging new levels. Every one of them seems to have been changed somehow so it’s mostly a new experience.
