Love the opening animation and especially the animation when you get the Cat Gun 3000 - so cool!
I am on an Apple laptop and unfortunately, control and arrows are bound to some window commands, so I couldn't change the yarn type. But I was still able to play the game and shoot the default yarn, which was really fun (great sound effects).
I did run into two small bugs, I couldn't move after the cut scene and another time, I found myself moving to the right, even when I wasn't touching any keys. Neither of these kept me from enjoying your game. I hope you get to keep working on it and, if you do, maybe offer some other key choices for the actions.
