I liked the concept of this. It hints at a deeper lore. And I liked the CGs especially. I never could get all the endings. I got all alive, all dead and a mix, but I couldn't get ending 3 - and thus couldn't do the others. Is there a trick to them?
I thought about giving a hint to ending 3 on replay just in case, but then figured the game isn't long enough for bruteforcing to be hard and there Are clues, so as long as the player knows it exists they should be fine
