Location of the 4th key in the abstract shapes world?

[Neonetik]

The other keys were all fairly simple to acquire or at least find, but in the world with the many long paths and shapes that form when you get close, I can't bloody find it! I've been searching for like half an hour and am totally lost!

Can anyone just tell me where the hell this ♥♥♥♥♥♥♥♥♥♥♥♥♥♥ is?

Hint: Look at all the "blood wells" and their cubes carefully.

Solution: When you enter that world, go forward and take the first path on your left. Then at the next crossing, take the left again. The altar in front of you is spitting cubes into the floating arch. If you follow the blood cubes, you'll find that there's an invisible path beyond the arch. Keep going forward and you'll find the key.

Cheers. Beat the game today. Great stuff. Noticed you made more games on your website or whatever. Any plans of bringing them to steam?
