Surprisingly enjoyable
Yeah, the animation wasn't smooth nor the greatest, however, unlike a bajillion other people on this site, you are actually aware that animating means moving things around; you know, so that things look ANIMATED.
And that is a very praiseworthy feat.
So yeah, even if things looked a little stiff, I loved how the little guy walked around, climbed things, walked past glass bottles, and all those little fun things that make flash and cartoons in general fun to watch. I give you high props for that, considering how as I said, most people do not realize that it doesn't matter how melodramatic you make your flash, if it's not fun to watch, then it's not worth watching. As I said, great job.
The only thing I feel you could've touched up upon is that you used that falling animation a bit too much; I think you could have shown him falling from a different angle or in a different way or something, in order to spice things up a bit.
But other than that, I thought the music choices were good, the animation was fun to watch, and that over all this was a solid and likable effort.
Keep up the good work, and keep improving your skills!
