The version of the game in the videos is a demo containing 15 levels. The whole game currently contains about 60 levels, many of which will be a lot harder and some more skilled based (more platforming) than those in the demo.
The first video is from TechnicalCakeMix which gives his thoughts of the demo. And he had some nice things to say!
The second is from Soleman Kirby, who plays through the whole demo in about 30 minutes, which is quite fast for the first time actually!
The game has developed quite a bit further since the demo was made. More music, sound overhaul, an ending, graphics enhancements and changes, new avatar in the works, bug fixes, optimizations, more options, more levels etc etc.
Basically it's all moving forward quite nicely!
We are still desperately trying to get through Greenlight though, so feel free to help us out! :)
Thanks for your time and take care!
