There are some noticeable polish issues, but I think the finished product largely rises above them. To get those out of the way first: the writing is prone to being overtly mechanical, some lines are pretty clunky ("The boss' hp is almost defeated.") and I would wager that like 50 % of all punctuation is missing. It's one of those cases where it feels like just reading through the script carefully a couple of times would help a lot. Art-wise, some of the ultra-saturated colors come off as a little haphazardly picked, and I'm not sure why Chris gets the most detailed design – to the point that it feels like it's stylized in a different way – when he's around less than the two other characters.
All that being said, the story is substantial enough for its short length. I like how organically it piles up blunders and how smoothly it weaves character drama around them. Where it goes it not exactly surprising, but that doesn't matter when the journey is easy to enjoy and the game comes off as consciously slight, just happy to show the reader some silly situations and a heartfelt ending.
