This is a pretty fun track to listen to and I can certainly hear it being played on a fast-paced retro game! Of course there wasn't much to go on by when comparing it to an anime opening other than a few things the others have mentioned. Incase you ever do decide you want to someday put an anime "touch" to your tracks, check out the 'Yo scale'. It's basically a scale used in traditional Japanese folk music and may give you a bit a crutch. Other than that, good stuff! 

Doesn't really fit the theme as it's more of a regular loopeable song, and doesn't build towards anything. 

There is a touch of Japanese game music. I like it a lot.

The square sound reminds me of games I love (like Katamari Damacy).

The best part is between 1'45" and 2'00". It could be in a Namco arcade game. I can see the home screen of a cute game like Puzzle Bubble. It's very well done. Congratulations!

This is a good track, I think it's suitable for cartoon movie or something. Also I like this happy atmosphere vibe u made. I basically have no complaints, except that you can slightly improve the composition and instruments. Nice entry!

Nice entry! At first I had difficulty finding the 'Anime' in it (though that could be my fault: I have not watched enough). At 0:24+ I started to feel it though! It might have also been because I will never expect chiptune to be in an Anime ;). So especially well done given the unexpected chiptune :D

I feel like the Anime intro would be over at 1:02 (it is a perfect end for it), but that this is the "full version" you always see on YouTube and such, which is always longer. Feels really nice!

There is only this one note that feels out of place at 0:55 - the last two notes of the measure. Feels off-key, a bit minor-ish, am I right?

And oh boy, 1:19+ is really nice ;)
