Much better than flips are fighting
The animation was a bit more smooth and the overall movie was much more dynamic and lively than flips are fighting.
I would recommend simply making this much longer than a few seconds since you have tons of potential to do things with flipnote.
while you are limited to 2 colors on flipnotes however this didn't stop other flipnote animators from changing colors in different frames or even thinking up creative work arounds for the color limitations of flipnotes.
While that is a bit advanced it is much more interesting than using the red brush for strictly blood whenever your stickman crashes into some spikes.
but it is the simple thing of simply making your movie longer is what will be your saving grace.
