SQIJ!

You're Sqij – a bird tasked with finding and collecting the six lost pieces of a holy tree – and bringing them to a sacred cave where it can grow. The caverns are full of nasties you'll have to dispose of, and you'll also have to find keys to unlock barriers that block parts of the caves. The keys won't look like keys – some of the inhabitants of the caves will give them to you. Can you find them?
