I'm running Xubuntu Linux 14.04, Oracle Java 1.8.0_45 and it worked mostly fine.
When I first did the java -jar on the Suzzle.jar, it crashed with an UnsatisfiedLinkError, so me being lazy and not wanting to deal with command line voodoo magic, I used Ninja Cave's Jarsplice to pack all the resources and run it.
I really like the minimalistic art style. It's really cool
I was happily playing along and got to the level that said "Ha ha" with the jump and the spinning laser, so I jumped over the laser and the game crashed. The crash dump is here.
I have some questions though!
1. Why are you using JS and what for?
2. How did you get the screen shake when running?
I'm very impressed that it runs smoothly on my awful 2 GB Celeron laptop while having Ecipse, a million tabs in Chrome, Skype, various folders, Sublime Text and two terminals open. Well done!
