Cathode Rays starts out simply enough (with only one ray to handle), but the difficulty quickly ramps up as you're required to thread the rays through tight passages and time your movements to match moving and fading planks. Soon you'll be trying to manage four beams at once in sparkly vector glory. Can you wrangle these ridiculous rays?

This game is not for the color blind....

I only wish that I was able to play it on a cathode ray tube screen, instead of my laptop, but hey, you can't have everything.

I can't be the only person who was amused that the review immediately before this one ended in this sentence. Turned out quite prophetic in an odd way. Perhaps the next game to be reviewed will be about leg warmers.


The jitter, combined with the fairly weak colors, makes it very difficult for me to distinguish between the various colors.

Please, developers, don't let your graphics get in the way of your gameplay. :-(


Okay, even though I can barely tell the colors apart, I still find this enjoyable. It's like navigating a maze with no walls, but the beams indicate where you can and can't go.

I'm up to the level "Broken". Can anybody help me here? (Thanks!)


While I understand the complaints about the jittery style and the way the colors are very difficult to tell apart, this was not a problem for me.

However, I did find the weakest link to be the inability to select your level. I stopped playing, came back, and accidentally selected "Play" instead of "Continue" (don't ask). Then I thought, oops, I don't want to start from the beginning again, and realized that I couldn't return to the one I was stuck on (Pieces - tricky one!).

Barring that, I think the color problems could easily be resolved (and it could still look amazing) if it could be reskinned retro-style like BIT.TRIP games or VVVVVV. Keep the great music (which I found very relaxing), just use bright colors with solid lines instead of the shakiness, and put all the art into the particle effects for starting and ending a level, level transitions and of course, when you break a line.

As for the game, however - I think it's another extremely original and well-designed puzzle with great levels that really make you think in a new way. I'd love to see more of this.


I seem to be stuck on Motion. Any help?



Slowly work your way clockwise up the screen for about 45 degrees, until the green beam is blocked and the purple beam is clear of the green panel. Then make a (relatively) quick break for the goal. Timing is tricky here because if you wait until the green beam passes between the two green panels you'll be too late, but if you don't wait long enough the green beam will hit the red panel once you're close to the goal.


My best so far:

10 Deaths in 5:50.

Can anyone do better?

I'm not able to beat the 'Motion' level!

Looks great but I can't see any difference in the colors at all.
