but UFO takes it to the extreme
Errrr...
no. It can potentially though, as can all other games. The point is moot.
You can sightread UFO chaining. And if you can't do that then you need to understand the two fundamental rules regarding UFO color changing.
extra is cool because one derp won't kill your run and there aren't st1 and st2 which you have to restart for an hour straight
The point I'm making is that it (Extra) has been described by many people as "lol-memorization" all the way through. Though, UFO seems to be more random (or "over the top"[not my opinion] in some cases) in its Stage more than any other Windows Extra at this point.
UFO would be 10 times cooler if the power system wouldn't kill any possible fun in stage practice
Define. And examples please. Keep in mind that there's only
one Stage where I would complain about Power being a pain.
Now I don't know about you, but I find it more fun when I can stay inside the attacks for longer. And more rewarding if I get out unscathed.
