The bad - collision detection on platforms, holes speed up when jump and can change direction, energy didn't seem to go down, can see some platforms on the right that shouldn't be there
The good - Better than the original version in my opinion, while faithful to the original I'm glad that the player can now move in the air when jumping, I like the 3D twist at the end and how you can look down the hole, that's awesome, also glad that you took out the things that made the original difficult and made it a much more reasonable difficulty level
