There have been some major changes since the last update.

Firstly, all the levels have been disposed of and new ones are in the making.

There are two major reasons for this change.

Firstly, degrees of challenge were pretty random between the levels in the previous version.
The difficulty curvature wasn't well balanced. From my experience, when people are learning a new skill (such as playing a game) there is a great improvement rate in the beginning. This rate of improvement slowly decreases over time and people generally plateau at a certain level. Hopefully this increase in difficulty will follow the natural rate of improvement for most players throughout the game.

Secondly, new mechanics were introduced which clashed with the way that the levels have been designed previously.
Major new mechanic which was introduced is the ability to dash. Dash refills whenever the player lands or when he collects a dash refill mid-air. This ads much more variety in gameplay and creates for a more engaging experience.
Some new obstacles were introduced as well such as moving spikes and fireball-shooting traps.

Happy scampering!
