+ Leaderboards
+ You can actually find some shortcuts which makes speed running the maps even more fun!
+ Simple controls and camera is not bouncing around
+ Interesting environments and unlockable marble skins
+ Minigame challenges

- Still some minor bugs
- So called puzzles didn't offer any challenge
- Too Short
- Not really worth 4,49€ imo

Awesome game!!! I would recommend this game to anyone who like challenges. It can be unforgiving at times but rewarding in return. I love the idea and concept of this game as I hope later on down the track there will be a DLC for more levels and other Mini Games for this, also maybe some extra mods for the ball other than the 3 that came with the game you have too unlock.
The game is challenging either way when using K/B & Mouse or XBOX 360 Controller, but can be played smoothly depending on what works for you.
Overall gameplay, graphics and music I am very content with what they have done. Shame the game has only 7 levels.
Graphics can be distracting and sometimes awkward when you have to move or view around to see where you have to go as objects sometimes block your vision.

Couple of minor glitches I had found while playing this game:
Random points through out the game the ball may either get stuck in corners or wedges.
Sometimes when jumping it doesnt always do it then and there. (Very rarely on odd occassions)
lvl 6 The TNT boxes sometimes get stuck and dont drop when needed too.
lvl 7 The last jump at the end you sometimes get stuck in free fall and forced to restart from the last checkpoint.

With only those minor glitches I have found, I still enjoyed playing this game and will enjoy playing it over again.
Personal rating: 7.5/10

The game preview misleads you to think you are going to be zipping by at Sonic speeds. You will actually be mostly crawling through the levels at a slow Marble Madness pace. Control over the ball also feels very loose and is easy to fall off the ledge on simple turns and narrow paths. The loose control also makes necessary speed and jump markers easy to miss. Small sections of the level will need to be attempted many times before a successful run. Personally, I would have had much more patience for this in the 80's and early 90's, but now I find the frustration level too great for mediocre entertainment.

On a side note, my system specs crush this game's requirements but still causes a complete system crash within 15 minutes or so. This too adds to my frustration with the game.

This is nice game to test your concentration and your control over keyboard and mouse.

Came into this hoping for a Super Monkey Ball-like experience, but unfortunately I didn't find it (nor have I found it in any game outside of Super Monkey Ball 1 or 2). It plays out more like a platformer where your character is a ball than a real...I'm not sure what you'd call it, but a game that focuses on the the physics, abilities, and limitations of the ball. The physics model of the game game is lacking, level design feels uninspired, and there are many frustration points with long jumps back to checkpoints. To top it all off it doesn't support controllers properly, only giving digital movement to the analog stick. Needless to say, that is the last nail in the coffin of a game in which your character is entirely round. Precision is important.
