This looks charming! Sadly, my graphics card passed away and at the moment I can't run RMMV games, but once I buy another one this definitely will be on my playlist. Reading the comments below it seems that the translation is kind of an issue, but I'm optimistic it won't suppose much of an obstacle.
I agree making a game while working a full-time job is hellish, to say the least. So don't be discouraged.
