I must preface this review by saying that I have never, ever seen grazing outside of a bullet hell game. What a brilliant idea.
This entire game is somewhat comparable to that, actually. It's like a SHMUP level, except without the shooting. There's even a boss!
The graphics and audio are top notch. Great, great job on the graphics with beautiful sprites + what I presume is sprite stacking, and if you hadn't told me that the music is from Kevin MacLeod I wouldn't have even known because it fits really well. What a great atmosphere you've crafted here.
There's not much more I can say on this that doesn't amount to any variant of "see, this is how you make a game in 3 days". One simple idea distilled to its bare essentials - steer with the mouse, protect yourself with a click, but executed masterfully. It doesn't need to be more than it is, and neither does it need to be less.
If I have a small criticism is that you'll sometimes want to read the dialogue text at the bottom, but doing so puts you at risk of colliding with something. I would suggest moving all dialogue to the top of the screen since that's where stuff comes from. I would also say that voice acting would further enhance this game's atmosphere and make reading more optional should you choose to make a post-jam update to this game, which I firmly believe you should - this is a great portfolio piece.
