Spoilers for the game: I played this a couple days after the anniversary of my dog's death, so right away I knew I was going to be crying. While I'm sure it's not your intention, some things in the game really hurt and I wanted to share my experience. 

I was already sad because my dog died of cancer so it was emotional having the ability to fight it. I got hit once (maybe twice) really early on when I was figuring out the game. Thinking nothing of it my experience followed as the game mentions something about dying, loved and together which sucked for me cause I wasn't able to be there when my dog died. I don't think that is an issue with the game however. Having the dog die really sucked, but then being told that I COULD have saved her reaaaaaally hurt. That did feel insensitive as having the player be responsible for the dog's death already really hurts but on top of that the fail state being "not being perfect" at a time you don't know you need to is unfair and feels bad. At that point I'd rather be one-hit and receive a "try again?" screen.

I hope you don't take this as me hating your game. I just wanted to share the perspective of someone who has lost their dog and also lost the game. Best wishes.

my first run got me homing + piercing + double shot + damage up + speed up i was unstoppable
