I've been meaning to get around to playing this one since you played mine as part of the Secret Santa thing we have going on in the forums. To start, you have a really great intro. It's a little tropey but hey, most of the best stuff is tropes done well and it seems like you're on the right track here. The mapping looks wonderful, very good use of lighting and fog effects, and it seem like you have a solid structure in place as far as mechanics are concerned. The music has a nice retro feel to it and suits the setting well.
There's not a lot of actual game-play in this early version so I don't have a lot to work with as far as offering suggestions but here's a few. Odds are, you've already tweaked some numbers and fixed some things so I don't know how helpful this will be but here it goes.
- Once I entered the swamp, I couldn't get back to town. It just kept sending me back to the swamp when I transferred to the town map from that direction.
- There was a couple of tileset issues. Nothing major. For instance, if I am all the way at the bottom of the inside of one of the houses, I can walk in front of the shelf on the wall. If I'm one square up, I'm behind it like I should be.
- The bees just seemed like they had way too many HPs. Thankfully, they missed most of the time.
- I couldn't open one of the treasure chests. It said I had to open it from the front but there didn't appear to be any way to get to the front of it.
Like I said, minor stuff. Very easily fixed if not fixed already. I like what you've got so far. I think your game is off to a really good start.
