I also liked the battles, except for when the computer went first.
Graphics arte pretty decent, but could use just a bit more work, as there were pixels everywhere.
Man, I wish there was a Pokemon game where you could use any Pokemon you wanted to and have the battles be exactly like this on Newgrounds.
Also, it should be rayed T because of the small amount of swearing, but that's the only real problem.
There were also glitches.
I lost the second battle to Frosslass, and when I retried, its sprite was still there floating all over the place, making it seem like there were now two Pokemon to fight at once.
Also, a few times the Health appeard Red for no reason. It was compltely full and instead of green, it happened to appear red.
Also, there's an HP bug. When I started the second battle and looked at the Pokemon to use,it only showed a part of the full number (Such as 9/92 for Dewott when his health was full.)
Other than that, this is absolutely perfect. And because of you, I believe I just wrote the longest review I've ever written. Holy crap.
