Just realized that: "Sorry for the bad English in the game, but I'm doing my best because I'm Italian and the project is made only by me."
I honestly wouldn't have caught on to the fact you are not a native English speaker. I can't remember ever seeing any glaring mistakes in grammar or weird-sounding phrasings in BH I or the BH II demo so far. Though it's been a while since I played BH I or tried the demo, so maybe I just forgot, which means any mistakes made were not that bad XD
... but listen, if you would like someone to proofread or see if any improvements could be made, you're welcome to give me a holler. I'm not a native English speaker myself, though, so take that with a grain of salt. But I still wanted to offer the help ;-)
