The premise (and the way love files are distributed, not your fault though) are inherently a little inaccessible, but if anything, the fact that you made a curling game with a screen resolution as tall as a curling field makes me like it more, because commitment to these kinds of things is awesome to me. I really like the idea of a video game that's as accurate to the real sport as possible.
If you decide to update the game after the game jam, I think it might be nice to explain the controls in-game & inside of the gameplay, but for now I was able to read the instructions on the page, so it was fine.
