Pretty nice little story game! I liked the gloomy atmosphere that was well realized and amplified through the detailed pixel art and moody music. There were certainly a lot of beautiful landscapes with nice composition in their shots, along with nice touches like parallax and fog. I had fun going back and forth in the story, retrying different decisions for various endings: surprised at some of the outcomes, like being able to walk off the cliff, or getting the kid to shoot you as part of toughening him up.
Unfortunately, as emotional as the game seemed to be going for, I unfortunately found the game too short to really make any of the emotional beats hit as hard as they could. For example, that twist of getting the kid to shoot you could've been a real powerful moment, but it would require a longer game that takes some initial time to really immerse you and make you love the characters: in a game like this where you barely know anyone and are used to retrying over and over, everything unfortunately becomes a bit comical, similar to how a horror game becomes less scary once you die for the first time and retry. Speaking of that, I also found that the language of 'game over' upon death made the death all the more weaker since it spells it out that its all just a game, nothing serious. Was also disappointed there wasn't a cool twist like you becoming the zombie in the beginning if you march out of the city and get the ? ending, and maybe you can fight back against biting the character, but that's me overthinking things and turning it into a weird time loop, haha.
Definitely a really nice proof of concept and does a good job at building a gloomy world in short order: would love to see a game like this become even bigger to make it all the more immersive and powerful.
