Games like knytt underground

Knytt Underground is a 2D adventure-exploration game with elements of arcade platformers and combining the mechanics of Knytt and Within a Deep Forest. It was developed by Nicklas Nygren and released in late 2012, with the PlayStation platforms seeing the first launch. Underground offers two playable characters, non-linear gameplay, multiple endings and a large number of side-quests and secrets.

Knytt Underground's gameplay fuses the mechanics of Nifflas' earlier games. From Knytt it borrows the freedom to climb vertical walls as well as being able to safely fall from any height (barring hazards like lava and acid, but unlike Knytt water is not hazardous). From Deep Forest it incorporates the ability to transform into a bouncing ball. However, there is only one ball "material" and different abilities must be gained by flowers that bestow temporary power-ups which are only usable in Sprite form, a new future introduced in Underground.
