Is okay, we got it's (maybe next patch).
Thank god I'm not a native speaker. Those grammar errors didn't bother me at all, because I automatically ignore them OR they remind me sometimes about my mother tongue, when you can skip words depending on context. Actually sometimes those grammar errors felt chill and hence fit well. made the characters special. I vote for keeping the "is" instead of "it's" at least in some cases. I liked those!
And TBH I'm pretty impressed about developer's english. Without some grammar errors native speakers wouldn't do, the dev could be a native speaker in my imagination. In other words: I enjoyed the writing.
And don't be so harsh. [The] Game is still in development. Sorry, I meant: Game
it's still in development.
