Jup, what they say be right.
A classic type of timewaster with extremely simple rules. The kind of concept that can amuse people for hours when executed properly.
That is, if it weren't so linear and devoid of variation.
The way things spawned no top of each other wouldn't be half as annoying if there was a proper way of locating your cursor... The current version of the game makes you rely on luck a tad too much.
Still, the concept is good, the music and soundeffects give it a lovely classicey feel, and it's overall quite enjoyable... but sadly not for long. It needs a bit of tweaking and expanding, is all. You say you're going to sequel the thing? I'm looking forward to that, ho yes!
