The consumer doesn't really care about how complex it is. The simpler, the better. Added complexibility would only mean more confusing code.

I wasn't talking about the last three. I was talking about the first three.
@hellrazer21: I don't know, maybe a library that needs you to pay for it. I meant that all of it was free, but there might be something else in java that I don't know about that is not free.

Now you're making me confused...     (random text... lalalalala for quote rule lalalalalalala  back on task)

It depends... it could be a throw in jar if it was logic etc. but if it was drawing code, you'd have to write it in yourself (or copy and paste)

Yes you did... Java-Gaming.org   

EDIT:
Multiple platforms is supported for all Java, 3d can be done in LWJGL   and most of java is free  

You could have a system like this:
Creatures have base defense, attack, dodge, accuracy, health, luck
Weapons add to attack
Armour adds to defence
if accuracy + random number between 1 and luck is larger than dodge:
if attack + weapons is larger than defence + armour:
damage done = combined attack - combined defence
damage done is deducted from health.
If health is 0, creature dies/whatever

Are you using LWJGL? Pure java? LibGDX?

No because people will start going "libgdx can do this, lwjgl can do this" and it will become a showoff thread for both libraries which there already are threads for.

@HeroesGraveDev, I am trying to stop this argument before it derails this thread and it ends up food for the Chitchat Monster 

You should definitely change that. 

  You're not helping... (insert random text for quote rule)

OK, everybody, let's just stop this argument. If you want to do LWJGL, then fine, do it with that. If LibGDX, then do it with that. It doesn't matter what you use. There is no reason why we should continue this argument. The OP can decide for his/herself.

Dont use

I think it might be because you had pressed a button while the game was loading so that it would not take any input. I might be wrong though  .

Could you post your player class please? And also, if you have code like that, please put it in pastebin.
EDIT: It could possibly be that you have no code in your keyReleased function.

Is it better to make cubes out of triangles or quads?

You click on the tick boxes beside the folders that you want to export in your jar (there's a triangle beside the project that expands the folder). 
At least on Eclipse Juno.

So it can only land on a black square? But when?
EDIT: I think I understand. You want to land on the green square, but it lands on the black instead.
편집 : 나는 이해할 것 같아요. 당신은 녹색 광장에 착륙하려는 대신 검은 색에이 땅.

That is easily fixed. (Please correct me if I am wrong  )

You would have a class called Square. That class would then be made into BlackSquare etc.
In your Square Class, you would have a variable like x, y. You would then have a class for Virus. You would then have a class/method to check if Virus.x is equal to BlackSquare.x etc.
I have made something to the extent here.

그 쉽게 고정됩니다. (내가 잘못 오전 있으면을 수정하십시오)
  당신은 스퀘어라는 클래스를해야한다. 그 클래스는 BlackSquare 등을 만들 수 것입니다
귀하의 광장 클래스에서 X, Y와 같은 변수를해야한다. 그런 다음 바이러스에 대한 수업을해야한다. Virus.x이 BlackSquare.x 등으로 동일 경우 다음 클래스 / 방법 확인하는 것이다
여기서 범위 무언가를 만들었습니다. (영어 링크)
(이것은 전체 설명입니다)

바이러스 카드가 녹색 광장을 찾을 수없는 문제인가요?
(Is your problem that the virus card can't find the green square?)
Got it off Google Translate 

I like the art style

Don't use sleep!!! >_> It isn't very precise.

I think you could make a variable that is like numberOnStack where If 0 then if mouse touching reveal and a function that goes when dragged all the other cards have their variable decreased...

Have a look at Eli's tutorial on game loops! 

On the topic of Rena's game, her game was not a game at all, it was an interactive book.

I have done a bit of pixel art (you will see more of that later  ) and I use a website called makepixelart.com. I then edit out the grey with pixlr.

It's really good.

It's good.

I don't think it's a penis and I'm proud of it.  Seriously, when I was in the level you are automatically put on, I was putting a key into a lock. But when I pressed E again, the game crashed.

Please put instructions in.   

I don't know why you need an artist.
