Congrats on finishing the jam!
Just FYI, the term endless runner refers to something else. This game would be referred to as a multidirectional shooter (or, since that term isn't super well known, more likely an "asteroids clone"). Game works well for what it's trying to do. The little goat creature made me chuckle. I like the art.
Not a huge fan of asteroids myself just because I don't really like the floaty movement, but that's a staple of the genre and this is a competent version of that.
Good luck with the next one!
