I had some difficulty running it on Mac OS X: it got an error while trying to load the level files. I don't think it was finding it via the relative path: you might make it easier by finding the path containing ColouredWorlds.love and setting it as the current working directory.

I worked around it by dropping the "love" app directly in the same directory, and then running in the terminal:

$ love.app/Contents/MacOS/love ColouredWorlds.love

A lot of fun, and good use of the theme. Never quite beat that 10th level. The 9th sure tricked me. Geat game idea! Would love to see it developed further.

Finished the game! Boy that last level is hard! Excellent game, well done.

Got it working on Linux by
1. Adding the LÖVE PPA (https://launchpad.net/~bartbes/+archive/love-stable)
2. Adding LÖVE with (sudo apt-get install love)
3. cd into the installation directory
4. run "love ColouredWorlds.love"

I really liked the concept of the game and somehow it made me feel like I am playing with Alice in Wonderland with each world and effect of itself.

It was fun and I liked the puzzles. Although some of them didn't quite feel obvious but generally got to it but I didn't beat level 9 I think (forgot which).

All in all it was really a good game.

Good work :)

Nice game, I had fun playing it!

Great mechanics and I love those transitions, graphically and musically. Just wish there were more levels, but I suppose that's one of the limitations of LD

Nice idea and fun to play! I also didn't get past the level 9..

Thanks for the feedback everyone!
And special thanks to micahcowan and Pcholt for giving instructions to run my game on Linux and MacOS X.

If you are stuck in level 9, are you sure you tried every world? The solution isn't what you'd expect...

Very nice take on the theme. Fun to play and original.

quite challenging, concept works really well! great job! :D

Nice game. The different world concepts were pretty easy to pick up with your level design. The only controls that threw me off was inverting the controls on the green world.

Neat application of the theme

this game is awesome. Really nice done!*

Too bad I already saw a playtrough at @AtomicVikings' livestream so I already know all the puzzles and such :P. I also think that inverting the controls in the green world was a mistake, since it takes some getting used to and didn't feel very intuitive even in the end. Although each of the worlds had their own melody they got pretty repetitive after some time. Good entry nonetheless!

I really liked the music transition. The world switching mechanic works nicely, and reminds me a bit of Quantum Conundrum. I like the trial and error approach, but some more consistent logic to how the world switches affect the levels would be cool. Very well done.

Dude that was sweet. Very neat puzzle solving.

Wow, brilliant entry. The musical themes are amazing, and the mechanics are sublime. Great work!
