There's an option to play it in English with machine translation. It is a little bit laggy for me at the title screen (probably loading the MTL). The main game works... but... ummm... the MTL is kind bad? You can guess what they're trying to say at least?
I think you'd be better off using Google Translate's camera since the MTL doesn't work on most of the buttons
Here's the MTL version anyways:
