Hey Kyle!
I've probably mentioned on my blog but I certainly don't belabour it ; but I am in fact holding down a regular day job in addition to being married with a child(they demand time too).
So yes I have done all this on a part-time or less basis.
I'm super glad to hear this project inspires some nostalgia for classic dungeon crawlers, thank you that's a big compliment!
As you can imagine getting that feeling right is critically important to appeal to the niche of gamers who love this style of game - so hearing people call it out from time to time is a nice affirmation that things are going in the right direction.
I apologize if you've already answered this, is this your full-time project? If not, kudos if you kept a day job while managing to get all of this work done man. Your project definitely makes me feel nostalgic for the classic rpgs so many of us loved playing back in the day. Can't wait to play a demo
