I only made the changes as I wanted to have a go at the game and it was the only way I could get it to run with the version of LOVE I have installed. I just mentioned it in case that was something you were thinking about doing yourself so you wouldn't have to duplicate the effort. I was quite impressed that those were the only changes required if I'm honest :)
On the controls, they work fine, just pressing left control when using WASD felt a little awkward for me. I only had a quick go on my lunch yesterday and didn't manage to finish so am going to have another go today, though what I saw was very nicely made. Well done!
