I can tell you tried

A few things: typos, lack of clear sprites, no real background.

Also, you had a technical issue when picachu was charging an electric "thing".

...

Arrow, not aero...and pikachu should have different picture/name...

Still need.

-Soundtrack.
-Sound Efects.
Then your flash will pass i think.

Pikachu Also Has...

... problems with spelling, gas, and blurred vision. I can say that there is some semblence of a plot here, and that's really the best I can give you. But otherwise, it's just a poor effort in every way: graphics are terrible, the animation is non-existant, the sound is erratic. It would be a good idea to go back to the drawing board. Practice some drawing skills. If you're just starting out, it doesn't have to be great animation. But lifting some pixel art off Google and moving it around a screen does not animation make. I'd suggest to refrain from posting more until you have some basic flash skills down pat, and can tell a story with them.

seriously?

oh my god that was fucking terrible! I mean seriously what was the point of even making that? U better not make a second part, I mean that wasn't entertaining in the least bit, and I mean that's not how you spell arrow! Just awful! I mean there wasn't even a fight, just a screen that said ..later on and then pikachu fell in this house and then the house ripped in half I dont even know what the fuck was happening there
