I really enjoyed playing this game. I think that there is a lot that works well including the style itself being a retro game-esque style. I think it adds to the cryptic theme and gives a sort of nostalgic feeling. The story itself is cohesive and nothing feels too jarring choice-wise allowing the tree of choices to run smoothly. As for what I think you could improve upon given more time; I think more images for each choice would make the story more immersive. I also think that continuing to develop and make the game longer would be nice to see.
Lastly, secret ending cool :3 for those who have found it.
