This has got some bumping tunes! Also I thought you started off really simple with the levels, which I like. There was one in there though were the green blocks were obfuscating the necessary path, so I got stuck on that. It was the longer rectangle one that had a big mess of them in the middle. The game really picks up when you add the red swirly guys, nice job!
Looking forward to hear what you have to say about Einnsámr :)
