Take your time. I can relate as I lost a very beloved pet of mine a month ago and it still hurts. Of course, it is a bit different as she was a leopard gecko (her name was Bella!) but I owned her for 12 years and she was a big part of my childhood. I still feel sad passing by the empty space and knowing she isn't there anymore. I'm a writer so her passing really gave me writer's block and set me back for a while. It takes time to get through things like this. Sometimes it could help writing about (or drawing in your case) a picture of your pet but is not an activity for everyone. I also had that paranoid feeling that my other pet, a 10-year-old pug would pass, and would often wake up in the middle of the night to check on him. I wish you the best of luck and hope you can move forward while still remembering the fond times you had with Kiara.
As for finishing the game, I am very excited. I love Legend of the Winged Ones and have followed the development of Bermuda Triangle since you first announced it although I've lurked for a while without many comments (maybe one or two!). I am thankful that you have kept us updated on your progress and I hope it is a big hit!
