Indika is a very short (~4hrs) walking game filled with puzzles and thought-provoking dialogue. Oh, the brilliant voice acting in this game... I loved the emotions that the 'narrator' put into his work. The ending leaves you hanging with questions in your mind. There are many scenes where you can't get what's happening because it's confusing or because it happens too fast.
I also want to state that I dissected the game and they animated every scene; characters are moving even when you don't see them in cutscenes or in the game. And the demon is also a part of some cutscenes, but you can't see it. They put real effort into this game. It's sad that it was short.
The downsides were pretty much the optimization and some less-polished parts of the game.
