I've completed this short demo and it was enjoyable.
I've found these bugs:
1. Dying enemy will become arrow sponge if shot repeatedly. I had to wait for it to disappear.
2. Opening Quest menu = map refresh. Very dangerous to do in map with enemies!
3. Frost arrow can't hurt bats.
I wish quest menu, aside of the bug, isn't needed to complete first chapter IOW completing all quests is enough without opening this menu. Also I don't know if it's possible but I wish quests only appear if Candy has gained respective quest.
