The game looks and feels right. There are some minor graphical issues when trying to look with your camera at certain angles. I would like a better indication of what corruption you can remove, at a certain point I spend about a solid couple of minutes retracing through the level because I was just that one bit short. I encountered two bugs near th 75% corruption mark. The last Island before the end cinematic. At a certain point you can jump off the map and walk underneath it. The other bug was that I wasn't able to glide or jump anymore untill I killed myself on the corruption.
But overall a good game.
