Really like the artstyle and character design! I'm interested in seeing where this goes with the setting and the themes you have going on. I feel for the main character, to me at least it felt like struggling with anxiety which is a relatable feeling.
Some things that did stick out to me was spelling/grammar, but just spend a little time on editing the script in the future and it should be fine. I also second another commenter's suggestion of some intense music stings to mesh with the more anxious moments of the game.
