A groovy little thang.
This really is just like the old blam movie. How did you get the colours so precise? Was it just by using old screenshots and a colour picker for reference or is there some easier way to get the gradients just right?
In any case, it was an enjoyable game to begin with at least, and rather inspired.
The game rules were pretty funky but it did get a bit boring after a while. Although it did start to speed up to about the right amount for elite guard as you said yourself, it takes a while to get there so by that point you're kind of getting bored of doing the same thing over and over.
Also, the music does get really repetitive. Whilst I appreciate you using the loop from the original file, it would have maybe been nice to mix it up a bit, or have that as a loop for the beats and have some other melody come in on top of that.
It sould also have been funky to introduce some more variables rather than have it just speed up.
Maybe have more than one file on-screen at a time later on? You could get clusters going across the screen, needing accuracy to pick out the correct ones...
I got 118 points and after playing that long, I reeally didn't want to start again and doubt I'll ever return to the game.
Maybe if you had a high score table I would though...
Still, it is really nicely thought out and a great tribute to a small part of NG.
