Oh hai! It's been a while! So many comments... Let's see: No, there is no way yet to "kill" metal in any way. Heated Sand makes Glass and yes, it stops acid. Electricity interactions aren't really implemented yet. Either way, electrifying a water body should only kill the fishs near the surface. And yeah, I intend to have raw Electro ignite C4 and Gun too. And Taiboss, the game's working. Try to refresh or use another browser. Lots of people are playing right now =)
@YuliasxPunk: Thanks! I think that SandTest is getting it's own personality inside the genre. Also, it's one of the two only falling sand games made in AS3 that I could find :) @deskup: Yeah, it would be better with explosions. I've worked on it and I can't find out a good system that doesn't slow the game down. The temperature system is working alright, the particles aren't cooling down :P
Heater/Cooler and LEDs are in the todo list, yup =) Multi? Find out for yourself! Gun IS C4, only in powder form. The blue stuff is the air pressure waves, which aren't functional and I keep them for the sheer awesomeness that they bring to the game XD
Uploaded new version! Google WireWorld for data about how to build circuits. People made computers with this! Also, there's a new element. A very useful one. Have fun!
Added the ants bug. My GF told me about the delete button idea yesterday so there will be one (Or two, I don't want to get the missus mad xD) They are computer virus, you can only kill them with computer acid =p The level loading is not working for some reason. I'll investigate (Takes out a magnifying lens)
I just finished an important part of the electricity system. Tomorrow will be left for testing and cake. It looks pretty damn sexy and will allow lots of new contraption mischiefs :)
@zonata2: The game is running as fast as it can, sadly. I could make it guess, but then we'll have the bugs that happen in Powder Game when you speed up the simulation. Pixels crossing pixels, interactions not happening and other nightmares.
@zonata2: I don't have enough time to update the game as much as I would want to, I definitely don't have the years that take to teach someone how to program and then how to make a game. I could point you in the right directions if you want though. Send me a private message ;)
It looks like tomorrow I'll have 3-5 hours to sit here and develop. I'm looking forward to adding electricity, as it will provide more complex mechanisms for you to build. Something like redstone wires in Minecraft :)
Fixed a bug with ant tunnels. Use the report a bug button, it's incredibly useful =) @zonata2: Oh, those ideas. Acid rain is kind of cool, I'll add it now to the todo list. Diamond, on the other hand, will be a low priority feature. (But one day it will be added!)
