A few hours in, and i've got three areas sorted out! You'll start out in engineering, where you'll go through a quick interaction with some other characters and some computers. Once finished, you'll head up to the command deck for your briefing on the strange ship that appeared!
I have to say, though it was daunting at first, I actually forgot to eat once I started delving into the pixel sea that is Bitsy's tile creation. I'm using a hack of the Bitsy engine that allows it to use 16x16 sprites, so I can squeeze a little more detail and use out of my environments. Obviously, i'm no master at this, but i'm happy with the result thus far!
It may not be clear in the above gif, but when you go up the stairs, I wanted the lower level to still be visible, just not accessible. I think the tiles i've chosen may be a little too complex in shape, which might make it hard to know what exactly you're seeing here. Regardless, i'm happy i've fleshed out this much in such a short amount of time (Especially for having never used this system!)
Onward and upward!
