Good graphics, but very poorly designed
It was overall a good game, i usually like games of this art style and the graphics on this game were pretty good, but the hope mechanic completely took away from it.
As your hope fades, the game gets grayer and grayer, to the point where everything is the same color. A perfectly understandable idea and pretty clever except for the fact that i ended up playing the entire game in grayscale, as regaining hope through prayer takes AGES. I placed my phone on the 'v' key and came back 3 minutes later and my hope was at about 80% full (i was close to sucide when i started).
Then there was start-up. In the game you begin with a quote, and a list of keys, with no explanation towards the purpose of those keys. I was pretty confused so i tried killing myself to see what would happen. All i got was 'don't panic', so then i tried praying and nothing other than yellow messages popped up. Surprisingly enough i was pretty confused. I only figured out what the two keys were for when i started praying to regain hope, then accidentally killed meself(>.<)
Next is Chloe. When i had initially started the game i had gone in the first cave i had seen. After getting lost about 30 times i had all the ship parts and bodies accounted for with the exception of the 'wires' and Chloe. So i did some exploring, found her, hit X, and lost an hours worth of work with no warning. At that point i was tempted to rate the game 0, because it would not have been so much trouble to write 'Are you sure? If you do it will end the game' -.-
Also a glitch i noticed: After i 'sacrificed my life' to enjoy chloe's company, There was an 'X' over my head no matter where i was. If i hit X then it would say 'you sat with chloe.....till you oxygen ran out' and end the game. If you hit it while you were walking however, the game would ask you if you would like to use all the ship parts to save Chloe. This made me pretty mad as when i hit X before, i had ALL the ship parts, but this option was never offered to me. At that point i had pretty much lost my all faith in this game. To the point where i didn't even want to waste all my time finding all the ship parts again so i could find the other endings.
So basically:
-Speed up how fast you regain hope from prayer
-At least explain the keys' functions. (for example 'pray to regain hope/color)
-Fix Chloe (so that if you have all the ship parts, as i did, you will actually have the option of saving her) and place a warning while you are at it.
-Add a map. If your concerned about a map taking away from the concept of exploration, then make it a shadowed map please (as snailmaster suggested)
-Fix the above glitch
As i've mentioned, the game had potential, which was killed, burned, and buried by the game mechanics itself. 3/10 2/5
