Level Themes and Unlock Criteria

The four revealed levels are all connected to the existing themes and branches, where every one of them split off from the respective branches of Day, Night, Dawn and Storm.

The levels are unlocked in pairs, where you need to clear two levels in two branches on the same side of the level tree to unlock a pair.

Can you guess which themes that are connected?

Oh, and there is one more level and theme we have yet to reveal, but we'll save that for later…
