you already posted this before, exactly the same. we have a wind now. i personally hate the dan-ball menu. "tends to be glitchy" - what do you mean exactly? everything has glitches. a 'virus' element is not advanced at all, AntB made one, behaves very similar. you can't complain of TPT dev's not coding stuff if you can't contact the dan-ball dev's and request them to make things, i'm sure they would reject a lot too.
Then you need to change how you say it then say glitchy stickman (combine with movement one) i never said perfect, and running mods is the same as official, it may need dll's though, its probably included with the mod. you say 'absolutely no contact with dev' yet you say this guy talks to him?
Powder game has less refined controls IMO, and the AI you speak about: it looks like they're drunk. They just seem to randomly move in my experience with them.
Powder Game is a messy conglomeration of elements that don't have any conceivable use for really "advanced" creations. It's pretty much designed for kiddies who go to google and randomly want to have fun with sillyness that looks cool.
...Powder Toy on the other hand, is an extremely complicated simulation game that doesn't even handle IRL physics besides the few instances where it emulates them like Air calculation and photon bending. All of the elements in it have been playtested extensively, and elements that don't have any significant use never make it into the official.
Rock-, it's not like the devs don't want to add new elements ceaslessly, more that we can't D:
If you want diff elements (unless they have actual use that can't be replicated with current elemets), then it has been made pretty clear you will need to code them yourself into a mod, or convince someone making a mod to do so.
