Quadroid
I don't remember it being so colourful. Especially the backgrounds.
But the gameplay is so familiar. The extra lines appearing... starting with blocks placed like a pyramid with spaces... a quad tile at each end... pieces floating to the top (which seems familiar, now I see it again). Also, the way
"Lines Left" is written seems familiar.
At the moment, I can't get past Level 6. I need to practice at it more, to get to the later levels (hopefully, those mentioned above), but I think this could be it.
Thanks Willcaleb.
