Do you have Java 8?

No, i have Java 7.

Do i need java 8 to play, i can install it.

Yes, the game is compiled with Java 8.

Ok, if i compile from source with JDK7 will it work?
or is java 8 absoultely required?

It should work. I did not use any "Java 8 only" structures.

cool o.O

Needs a epileptic warning - random but fun! I included it in part 5 of my MiniLD #56 compilation video series, if you want to check it out :) http://youtu.be/9WPYv0fMzvM
