Wow the graphics are quite impressive and original! I'm not always 100% sure what the impact of my mouse is on the game, be it's surprisingly fun to replay the game a few times to try to understand it more. Congrats!

Crashed and zombied on my mac, not really sure why.

Well this was an experience. Odd.

As an interactive art piece, this is fantastic. It's got some replay value, which is good. I wouldn't know where to start creating something like this. Very well done sir!

I enjoyed this experience! The audio elements were well put together and I liked discovering what mouse actions moved things forward.

Awesome look and feel as well as audio.

strange and beautiful! not sure if this really can be called a game but a interactive music-visualization :D Anyways, I had fun and enjoyed it!

:O That's sublime. Can I listen to more of your music somewhere?

That was... amazing, really, i enjoyed this experience.

Thanks everyone for the nice comments =)

@Danik : Sure, on my website (not updated since a long time) http://clement-musique.c.la or my soundcloud (search for Spotline)

Is this what we call synesthesic orgasm?

I won!

Beautiful. I love the art deco fonts and then I hear the music and eventually the show starts.

The issue I have is it feels more like a demo of something and no real game play element I could see.

Really nice audio :D It was fun to play around with!

This.. this... thank you for this experience.

This is awesome! I really enjoy it! It's abstract and beautiful, and... Well, you know what, I'm speechless. *five stars*

Couldn't get it to run on my Mac (running Mountain Lion).
Screenshots look awesome!

Amazing audio and beautiful visuals! It's quite an experience. Not much of a fun experience, but an interesting one.

I have OSX Lion and it works just fine. Maybe the crashes are a Mountain Lion specific bug.

Trippy, great mood here

Yoyoyo,
Beaucoup aimé ^-^...
A un moment j'ai pas compris si j'étais bloqué ou si c'était la fin par contre.

I've spent 30 minutes playing it and I have no idea why. I basically drowned in it. Great interactive art piece. Well done.

Beautiful!

Not much of a game here, but visually impressive. The audio is awesome too. Well done, man!

Great graphics and music!! :D

Erm.
This is not a game.
It looks cool and everything, but this is not a game.

Really cool graphics and sound! It's neat to see a little forest growing, and I like how we can select the colors! The color effects are very neat, too.

Cool as heck

Interesting choice of lack of indication on how to use mouse.. Really enjoyed the graphics style.

Beautiful experience and well worth the second play through, the first time only the one tree grew but the second many did :)

Although some people complain that this isn't a game, I am glad that not all people are constrained by what a game is or we wouldn't have this amazing art game! (There is no category rating game like elements and this whatever it is rates highly in Innovation, Fun, Theme, Graphics, Audio and Mood.) Innovation is as much about what elements we can remove as we can put in.

Wow! I was actually looking for some kind of an art-game and I've finally found it. Thank you :)

So great, loved it!

Awesome as hell. This is a bit like something I toyed with before going into a more gamey direction with my project. Sweet to see someone do it better than I could ever have done. Great experience.

Looks more like an interactive presentation than a game, but I liked it

Well now... this is fantastic.

Just read the comments, (I write mine before reading others).

I also believe this to be a game! You have to do things to make things happen, like in metal gear solid. Only this has fewer giant robots... (of course, it has many more, they're just over horizon, waiting for the perfect time to attack...!)

Anyway, rad *game* ;)

Wow, without the "humor" field, I would have put 5 stars everywhere. I agree with what you said, everyone should play it a second time.

Wow I can't describe or really even, that was... That is... so goddamn wonderful T.T

really well done.

Very controversial. It's more art than a game.

Wow, that was amazing. Great work...

Really nice experiment.

Brilliant! I love it. Very nontraditional but very cool.

Not really a game but a nice demo. The interaction is too much guessing by making random mouse moves so it's a bit tedious but the sound is really awesome.

Thanks everyone for the comments ! As it seems there's some talk about whether this is a game or not, I would say this : maybe it's not. But I believe the definition of 'video game' has now become wider than the definition of 'game'. With all the recent contemplative video games in which gameplay is secondary, I really think this entry belongs in the competition. Even if the gameplay is crappy =)

Wow ! Amazing experience, certainly the denser game of this Ludum Dare.
The graphics, sounds and music combine perfectly.

I'm pretty sure I took LSD. Or maybe I just played this game. I can't tell. I can't tell anything anymore.

I really enjoyed it.

Spotline, this is really cool. I'm sorry that some people would rather waste their time defining what makes something a game (that most tedious and pedantic of activities), but I'm happy that you spend yours actually making stirring games like this that push things forward. To the other people--emotion and innovation are just as vital to games as any other artform, the days of defining a game by achievements and the number of guns it has are over.

Really great atmosphere, a nice place to spend some time. Audio and visuals worked well together. Excellent overall. I liked the artsy approach but equally would love to play a more traditional game that looked and sounded like this

Thank you for creating it.

the music and art style really bring it together, great job!

I like this, will have to play it a few more times.

I was unable to get this to run on mac at first, I had to go into terminal, go to the folder with the program and say

chmod +x Cosmogonie.app/Contents/MacOS/LD24

I think using 7zip broke the macintosh version.

This was super pretty, on my first playthrough it was a bit frustrating because I could not figure out what was supposed to be interactive or when. The main thing that confused me was what the keyboard keys were supposed to do. They usually, it seems like, would move the mouse blob somewhere off the top of the screen; and then sometimes something weird would happen. I think maybe I was hitting debug keys I wasn't supposed to be hitting. What I eventually realized is that at least some of my confusion was because playing the game on "good" graphics made a lot of stuff seem to not work right, like things were not responsive to my mouse actions. When I played on "fastest" suddenly the whole thing made way more sense. Anyway neat little piece of art, though I'm still not sure if I am seeing the intended ending or not!
