Hey, this is a very nice little puzzle game. I liked the controls and even when I forgot to select the correct color it was nice that I didn't have to "switch off" before changing the color and continue to make the line with new one. The concept is great, graphics are well done. The only thing I found reaaaally annoying was that short music loop. But I finished it none the less :)
Congrats on good first entry, keep up good work!
