Better go with the most well-known pc games / characters, instead of these that a very few ones recognize, and the gameplay too, and the music doesn't fit at all.
These looks colorful, pretty, but kind of pretty simplistic, something is missing, maybe a BGM, or some kind of other animation together, but as they are now, are not that good.
Man, please fix the DS theme, because the gameplay screens are streched and looks awful that way, so you can see that you need to adjust the DS screen before recording the theme.
And the Wii theme, please change those lego characters for some other iconic good ones, they look horrible, being honest.
Seems you really know which is the right touch of these.
Personally, i prefer the v2 (the one that have a music instead).
Please create more of these kind.
