/vr/ - Retro Games

So. I've been playing pic related and having a blast. Having just played more modern JRPGs (SNES and latter), the need to draw maps on a notebooks is amazing. But it has its downsides.
I'm at the part where the game opens up and tells "fuck u", the dungeons are much larger than before. And its not the size in itself that is the problem. The thing is that I can't predict how the dungeons will turnout, so I'm liable to run out of space, even at the start. I don't want to waste 1 page for each floor and have 50% of the page useless because I started drawing at the center.

So. Are there any Android software for cRPG map-making. A companion for dungeon exploring. I say Android because comfort. I'd rather not alt-tab every second.
Most programs that I've found out there are geared towards creating maps for table-top role-playing.
