  • TechZ2124: Congrats to @Doughnuts108: ! Another time you stole me my gold ;) And congrats to all the others entries, most of them were very fun to play !
  • pajlada: @keeghan: I'm sure a lot of people tried their best and didn't win, that's just how it goes. Everyone can't win.
  • keeghan: @pajlada: COME ON! I TRY MY BEST AND I DIDN'T WIN!
  • Andr3w246: @Alfajim: Ah. Sorry. I got confused.
  • Alfajim: Congrats to Doughnuts108 and TechZ, and everyone else for some excellent entries. :)
    @Andr3w246: its not decided by likes, its decided by sdac and pajlada, would you prefer bad builders to win instead of the good ones? : )
  • Andr3w246: :-( I don't like how the contests are decided by likes... All the good builders will just keep getting crowns! (I'm not complaining that I lost. Just saying)
  • that guy2: @TechZ: @Doughnuts108: a stalemate resolution associate will arrive shortly.
  • WXWMC: @FirePhenixFire: help pajlada to reply you:as you wish.
  • pajlada: Thanks for the great entries! We had a lot of contenders for the trophy spots this time around. :)
  • FirePhenixFire: @pajlada: you should make a rule that @TechZ: cant get any more gold trophies ge can only get silver ones :D
  • pajlada: @mznznlt: isn't a random sorting of levels good? that gives everyone an equal opportunity to be at the top while the contest is still running
  • pajlada: @mznznlt: Unless we have a question regarding the wish, or if we can definitely say yes/no, we probably won't respond to wishlist posts, as the response would serve no purpose. however, if you post on the forum you can be 100% sure I have read it within 10 hours of it being posted
  • mznznlt: Also @pajlada: , could you make it so the levels in the contest screen are sorted by amount of likes? Right now it seems random, with like sorting we could see the best entries on top. And i feel ignored in the forums wishlist, in my robot equiped lua topic.....
  • mznznlt: @TechZ: Now we know who will win again......
  • Technomancer: @TechZ:awesome entry!!
  • TechZ2124: @shantanuaryan67: Just did it ;)
  • shantanuaryan67: @TechZ: wating for ur level when will u release it..?
  • pajlada: @The_Blacksmith_: You will have to use your own judgement, it's hard for us to say whether there has been sufficient modifications or not before you upload it.
  • cooldude: So manny entries
  • FirePhenixFire: @TechZ: stop geting all the gold trophy it makes it so mutch harder to get one
  • The_Blacksmith_: @pajlada: If I fix up an old level can I enter it?
  • Andr3w246: Who likes trains? Because that is what I made!
  • abrackers2: Done the shell of mine. Quite large :)
  • Technomancer: @TechZ: its sounds cool
  • TechZ2124: @Technomancer: It's a surprise ! Ok, a hint : unreal heavy vehicles made by TechZ's company :)
  • Technomancer: @TechZ: what do you gonna build?
  • electro: Working constantly and hard on my level. That level will rock principia!
  • Andr3w246: @TboltBeardie: I think. That's what I build.
  • TboltBeardie: @pajlada: I'd assume it means any form of large machine-esque builds.
  • Andr3w246: @pajlada: OK. I was just wondering.
  • pajlada: @Andr3w246: We have no concrete definition of "heavy", so you can use your own definition :)
  • pajlada: @cooldude: Very happy!
  • Danish18aiman: @incrazyboyy: more like 11 days (14 July)
  • cooldude: @sdac: now a new not old entry happy?
  • Andr3w246: Hey peoples! Got my entry in!
  • Ctjet: @abrackers: lol
  • abrackers2: @sdac: me saying I would prefer it to run till Wednesday was before I read about you increasing to 14th. Thats even better :)
  • abrackers2: @Ctjet: well at least you seem to think rockets should be allowed so hopefully my level shouldn't be disqualified
  • Ctjet: @sdac: gah i dont like the no old levels rule because i cant submit my build your own rocket 2 level
  • Andr3w246: @sdac: What defines "heavy" in heavy machinery?
  • abrackers2: @sdac: well mines massive and a machine but its not exactly machinery but oh well. I would prefer if it were run till wednesday
  • Golden: Hmm
  • keeghan: @sdac: I hope, it going to be a transformer boss + big and heavy.
  • sdac: @keeghan: do what you want and if it's good enough it can win
  • keeghan: @sdac: can I make the machine a boss?
  • teslos909: Неплохой конкурс, однозначно учавствую! :)
  • electro: @sdac: ok
  • sdac: @electro: it doesn't have to look good. any object is allowed as long as you don't abuse it
  • electro: @sdac: fast reply please
  • electro: @sdac: is our thing must look good? Any non- good-looking but effective thing will work for contest? All objects are allowed?( stabilizers, rockets, thrusters, etc.)?? Please reply fast. I think I can take part in it ;)
  • keeghan: @sdac: can you make the marble fall contest next?
  • TechZ2124: @sdac: Thanks a lot, looks like I'm gonna make something even more epic :)
  • incrazyboyy: @sdac: really? yeah, you followed my suggestion! thanks
  • sdac: @TechZ: @incrazyboyy: Contest now ends on July 14th, so you have more than a week to build :)
  • TechZ2124: @sdac: Please give us 7 days. Build something big and nice is already hard in one week but even more in only 5 days ! And the topic of this week requires a lot of time to create an entry because make a heavy machinery is quite complex. I started my entry but I hope you understood that I might not have the time to finish all what I want to do in 5 days.
  • sdac: We might run it until wednesday if there's enough interest
  • incrazyboyy: 5 days!? That's not cool, I won't take part!
  • abrackers2: Oops, meant @rom1k: @sdac: , not @cooldude:
  • abrackers2: @cooldude: not entirely sure it counts but what ive got is definitely heavy
  • cooldude: Come on
  • rom1k: @cooldude: Sorry, old entries not allowed.
  • cooldude: Enterd again
  • cooldude: First one to enter
  • sdac: Good luck everyone!
