why do some peopel have blue names

i am a argentina in latvia i found this by serching free building game on youtube i dont speak good english sory

This is semi-automatic but can someone make it shoot automaticly?

These are a list of bugs that are known or common. If you post a bug that is already mentioned in this list, your thread will be deleted. If you do it multiple times, you will be warned. Ctrl + F if you want to find your issue faster (in case you couldn't look through a few issues). Unless your bug was reported BEFORE this thread, it will be deleted. Any threads made after this thread will be deleted or action will be taken depending on the situation.

Known/Common Bugs

• Achievements take a while to receive
  
• "Bug" for losing posts is not actually a bug, but when your post/a thread with your post in it is deleted, your post count is lowered as well because you posted there. It's not a bug when your post count lowers.
  

This will be a replacement for the failing Rotten Bridge to Nowhere. Basically, you have a small map and you have to run around to avoid meteors smashing onto the ground. It was very successful on Roblox, and I'm hoping it will be just as cool on Buildism.

Er... it's kinda hard to beat the coolness of a huge meteor smashing into the ground, exploding, and then watching the fragments going flying in 3D though... But I'll try

I can't find it on the wiki, and it doesn't seem to be the same as on roblox

Today I woke up in my friends house because we planned to take a game time together. On the morning I took Oboy with milk and took a bread. When I ate 'em I went home. Then, a bit later my little sisters friend came home to us. They went together into a pool for swimming.
I was at the trampoline with my little brother. It was fun. And now I'm at the computer.

--Be nice Game--
You have to say something Nice about the user above.
Example: You are nice because (Ex. You are very helpfull for everyone)

Hello, My name is Happyman.
I'm too Happy.

I'm helpful and nice to everyone.
Yes, before I joined my little brother (nice) told me everything from this site.
So, Hello buildism world! ^_^
