Could not run on my Mac. Jar Launch Failed!

Could you please run it from terminal by java -jar name.jar and send me the output? I don't have any Mac, but it should work...

Weird, could you please provide output of the game from terminal?

On Linux I get "java.lang.IllegalArgumentException: URI is not hierarchical" from WorldLoader.java:108.

Great music and art, but it suffers from the mundane gameplay. The platforming was painfully difficult. Overall still pretty nice.

Player takes a really long time to stop moving considering how small some of the platforms are. Nice job on the audio. Ran fine on windows.

Pretty cool, I liked it. Platforming was a little difficult at times but the idea was cool, the music was cool, it was pretty cool, Lol.

I can only describe the movement as "floaty", but the main menu sound is very cool and I really dig your portal transition effect.

Overall a solid attempt, though I think the major thing holding it back is the acceleration/deacceleration on your physics. It makes everything feel way too slippery and winds up being frustrating to play. Couple that with having to start all over after death and I don't feel like continuing to play it.

The portal transitions were freaking awesome though. And I think the music and sounds effects were pretty keen.

So nice graphics,good work!

So nice graphics, good work!!!

Unfortunately, it crashes on my Win 8.1 64bit. I ran it from the console and it gave me this output:

(Yes, I was there ;) Contact me on Twitter, if you want.)

Very nice music and smooth gameplay only the friction on movement is way too much. Good work overall :)

We have actually considered making the movement less "floaty", but we decided to keep it for the.... "hardcore" feeling (ok, that is bad excuse, we were just lazy, but it is completable with little bit of practise :D)

Maneuvering was difficult, but that was part of the fun. Great game and good luck to you!

Nice job, I liked the graphics and the sound, kinda retro :) The physic is a little annoying sometimes but it's a good game. Good work

Looks nice, but the platforming is really hard, even harder than in my game :-p

Runs fine using ./start.sh on OSX for me. I agree with the other comments that the character sliding around made the game a bit frustrating, but I enjoyed jumping on the green things :P I love the pixel art graphics :D

Nice art and music, and some pretty fun levels :)

The controls felt a bit too floaty though, and it was especially frustrating to jump and land on small platforms when I'd often slide right off them again.

Nice, really liked the platforming and the level design! Like people have said before, you should set your friction a little higher.

Nice little platformer! I liked the idea of rebelling against the end of the game, and I died in all hummiliating situations because of it: the G of "Do not go", the last jump of the other E, and so on. Levels and jumping need more polishing, but it was nice to play!

I was unable to get the Web or Windows version to work. Checked I had Update 55 of Java installed too.

@sikosis - what about console output? The "All platforms" version should work. But yes, there is problem with level loading on some computers, I don't know why. At least, you can try the C# clone from web
