Apologies for a bit of a long comment but I want to gush a little about why this is my favourite LD34 game so far. Damn.
This game has some beautiful graphics, beautiful audio and sets the tone perfectly. But more than this, it's the subtleties in this game that make it. First off, the silkworm collection blends so seamlessly with the music I didn't even realise it wasn't part of it the first few times. Very cool use of dynamic music.
Second, whether intentional or not, the spear traps in this game actually produce a misdirection that makes for one of the most minimally designed puzzles I've seen. Despite the fact that the spears rise up and down, usually you can simply fly around them. When you reach the worms completely surrounded by spears, the simple answer of simply waiting until they were down didn't click for a minute for me because there was 'no way in' and I was still thinking about them like I had all the others, as simple obstacles to avoid.
Third, the use of negative space is fantastic, and flying over blackness to arrive at more map produces a feel of sequence breaking despite the fact that the game map is entirely open.
Kudos.
