A crow somehow stuck in a crystal cave! (and there is a boss that shoots and kill stuff)

PLEASE READ BELLOW!!!

How to play:

downloaded version has glow turned on

• -`W` for jump (jump on air will cost you 1 point of mana)
• -`A` & `D` for moving to left and right
• -`S` for gliding (cost mana, too!)
• -`space` for interact
• -`K` for attack

This demo game is not yet completed (not feature-complete). I want to take a good rest, fix my motivation and find my joy back. While I am taking a break from the development (this means the whole development is put into a halt), you can enjoy the unfinished version..?
