This was an interesting concept and the music reminded me of SEGA games. I wasn't a fan of the "turn based" movement but I have to admit that it was an interesting decision and overall added some puzzle elements to the game which is a nice twist. Your daughter did awesome work on the art :) From visual aspect the game felt like a single consistent unit and accompanied with retro music felt nice.
There are a few comments I would like to point out for possible improvements:
1. Your buttons blend in with the background/game on the main menu. Would be better if the background was less visible so the button would hold more attention (call to action).
2. Scaling was a bit of an issue. You can look more into it by setting correct Stretch mode & Stretch aspect IIRC. This is not a major issue but would make your game look better.
3. Don't be shy of using custom fonts. Minimal effort but correct font can greatly improve presentation of your game. This is mostly for UI elements & instruction popups.
Hope these will be helpful and you had fun working with your daughter :)
