Interesting version of a rhythm game - love the graphics! You should limit the keys for playing music to maybe 5-6 max? I found it tricky just on novice! :)

I like music games. I'm a musician as well as a very good typer but I found it very hard to hit the right keys. I think the spacial layout on the screen messed with my brain and I always hit the wrong keys :-D

I agree with the comments about there being a few too many keys to hit, but overall this is a solid entry. Well done.

Interesting... I find it was a bit frustrating that a note vanish the first time when you fail at it. Moreover the first time is the harder, when you have to figure out what rythm is the note. I guess this choice come from the evolution theme ( weak experiment die first way ) but I'm unsure it result in good experience for player.
The rest of the game is pretty good, I really enjoyed play a it, the evolving FX are good and really add to the mood of the game

Thanks for the feedback people. Many design flaws because I'm too "inside" it -- for example, I can read the timing of the notes based on their spacing. But of course hearing it should be an option at least once!

This is great idea. With a bit more polish and balancing it could INCREDITASTIC.

So: How does the "Evolution" of it work? So far I can tell the notes that you can play remain, and those you cannot hit will go away, so after some time "your song" evolves out of it.

Solid idea, but in practical terms it'll results in monotonous, easy-to-play tunes.

Solid concept. Main complaint? The 'i' key is too hard to distinguish.

Really interesting! I love rhythm games so it's awesome to see them attempted in LD.

Stuff that might help:
-Having the cursor go left->right then jump back makes it a bit harder to read (especially when it's fast) - this is probably why most rhythm games scroll the camera along with the notes.

-All the stuff in the background is kind of a distraction too, but I like how it looks so I'm torn :)

-I think the most difficult part was how the keys were spaced out - having them all on home row would make it a lot easier. (Maybe easy mode -> home row, hard mode -> all keys?)

-Seems like certain keys didn't necessarily correspond to the same notes (or 2 keys would be the same note) - having a unique correlation would probably help musically.

-Having some sort of randomized bassline would also be awesome musically, instead of just the note melody.

-Sometimes it said I hit the wrong key when I don't think I did (rather, maybe I hit the right note but at the wrong time)? Maybe check your scoring algorithm to see if it isn't too eager/trying to check against the wrong notes (I think it might happen more often in fast runs)

-It's not really clear how/why you fail, having some sort of obvious life bar would be good.

Overall this is a really cool idea for a game, I'd love to see what else you can do with it. Great job!
