One of my favorite iterations on the theme so far! The story and the gameplay alike are nice, simple and efficient, if you plan on polishing this further I'll keep an eye out
I'm seeing in other comments that you needed to shoot letters to "unlock" them for the dialogue options - i thought you just needed to survive the two minutes to gather your courage or something. This is a great design idea so it's a shame it's not conveyed as strongly as it deserves! Perhaps a simple change you can implement is only having the unavailable letters grayed out in the dialogue option? That alone might make it more clear that gathering individual letters is the objective
