Well all I can really say was that I really didn't enjoy this too much.
The first problem was obviously in the visuals themselves, and that's practically the biggest thing in a cartoon. The characters, backgrounds and just the artwork in general looked incredibly flat and two-dimensional, I could barely sense any depth in anything. The characters were all line-tooled and when they moved around it was extremely stiff and the motions just seemed awkward. Occasionally it looked okay and had a nice flowy look to it when you used easing on the tweens, but the rest of the time it just looked cheap and off, it was simply unpleasant to me.
This issue showed especially when the characters were running, there was no bouncing motion or really anything to show that force was being put behind the movements. Sometimes the perspective got all distorted, like when the camera was zooming out of the two on the planet for one example. Also the lip-syncing, it matched with the words they were saying, but it was just one picture for each sound, their mouths kept blinking to different frames. It beats mouth-flapping, but it still wasn't so great.
The colors weren't really interesting, just boring, dull shades and muddy-looking half of the time. I didn't find them appealing.
When they were running from that monster, at some parts when it zoomed in on them it looked pretty good since you put eases on the tweens, but the lack of music, ambiance and overall sound effects in general made it so dead. It was just boring.
Writing was okay but again, kinda boring, everything was so slow-moving and I just wished the whole thing would hurry up and end already throughout the whole thing. Voicing was alright, the robot guy sounded good, the other characters were kinda bland though.
Overall I found it stiff, flat, slow-moving and lifeless, could've been so much better.
