I don't see the Sculptor doing anything odd, except facing the wrong direction. Using a walk command to set direction can be a bit unreliable, it's better to use _face (0 is right, 90 is down, 180 is left, 270 is up). Or you can use { _face = _direction_to(@) } to make them always face the player. I'm going to try and make walk commands more reliable in general, they still seem to fail occasionally seemingly at random.
The boss feels good, though could still use a bit of polish (EarthquakeWarn as a slow implosion, followed by EarthquakeHit as a fast explosion looks good).
I've fixed up a few things with large numbers of effects on-screen; now sprites with "Is Effect" checked should cause much less slowdown. Still haven't figured out the stattaco framerate bug, though I am slowly tracking it down. Since it only shows up on rare occasions, testing is tricky.
I should mention that objects in the foreground always appear over objects in the main layer, which can cause some weirdness when spring-jumping in front of them (for example, the cactuses). Mostly I've been handling this by making small, stationary objects into sprites, this is the reason for the above (if you make them Effects and then use a solid tile to block them off, they cause much less slowdown). I would like to figure out if there's a solution for objects such as these in other games... 16-bit RPGs had it easier by just not allowing the player to jump too high.
I've decided to make my story a bit more broken up, instead of putting it all into one single world. After all, BoundWorlds' demonstration story should probably include the idea of travelling between worlds in it. I'm still going to be keeping the same main characters, but they will each have their own world, with the final world being unlocked after the others are completed.
The basic stories I'm working with are as follows:
In the North, a force of darkness from the frozen wastelands threatens to overrun a society of lords and warriors in their mead halls. A brave hero stands against the endless hordes of monsters, but who is this cloaked traveler and what purpose do they serve?
In the East, a peaceful society of mountain nomads finds themselves troubled by dreams of endless corridors and visions of strange worlds. A young flutist awakens to find himself with strange mental powers, and a person who appeared in his dreams now seems to exist in reality.
In the South, a desert kingdom built upon the ruins of an ancient civilization is troubled by raiders who seek to conquer its holiest city. A temple dancer finds herself questioning everything she thought she knew about her gods when a wanderer from ancient myth appears in person.
In the West, a secret rebellion against the ruling king is slowly growing. Courtly intrigue abounds, and few nobles bother to notice the ramblings of a half-mad playwright or the mysterious cloaked vagrant that has appeared in their midst.
In the center of the world, a great tower has stood untouched for centuries. It is said that whoever climbs to the top will understand the true nature of their world, but knowledge may come at a great cost.
