This was a really neat game!
I really liked the scribbly artwork and heavy use of dithering. It really gave the game a stark visual style and helped sell the creepy tone.
I also really like how the creepy atmosphere slowly grows more apparent as the character struggles with their actions. It really adds to the narrative drive of the game and helps visually emphasize how they are feeling.
One thing I think that could be interesting to expand on would be additional dialogue after certain triggers or maybe even different paths/endings the player could find. One example is on day one where the player character realizes they don't have any money. Out of curiosity, the first thing I tried was going back to the house to see if there would be any different dialogue with the character's mother.
Overall, a very interesting experience. Well done!
