That's awesome. I didn't know there was a difference between hacks and hacking styles. Well, you learn something new everyday. Thanks! That means a lot!
If you'd like to see a few things on umbra, check out my Deviantart Page. My username is Tyrozz. A few minor changes were made but not something that changes the entire style of the map(s).
Sorry. I've been working a lot so I haven't been on PC in a few days. Yes! I am the creator of umbra. It's been okay. For me inserting tiles is a bit of a bug and deciding the outside layout of the Academy is a little rough. But I'll hopefully have a beta out by the end of this year.
