This is really two updates in one, I think.
First off, here's a timelapse of me mapping out a screen/area/level. Or half of one, at least. This was over the course of about an hour.
Here's what I did today - a bit of post processing with some fog effects. Just to give the place a bit more atmosphere.
I also figured out how to work treasure chests properly, though I guess that wasn't too big of an accomplishment - just a short move route and a switch statement. But I hunted down some custom sound effects for them anyway which were pretty cool, if I may say so myself.
This forest area has another few screens/areas for me to finish. Two large maps, along with a couple of small ones. It's grown quite a bit since my initial plans, but I like it better this way. Feels more like a place you could get lost in and an actual dungeon-ey type area, rather than a few screens players are able to rip through with ease.
I'm hoping to draw up some more character/enemy sprites soon... but map making is proving quite addictive at this stage. Whatever happens, I'll keep you guys updated.
