Low maintenance
Require little attention. You can run it along with Tamago or another Tamagotchi. Press the C button to check if your tamagotchi is happy or upset. If it's upset, it's likely that your tamagotchi either hungry, unhappy or both.
Normal character pixel is much bigger than Tamago
Normal character pixel that walks around the screen looks bigger than Tamago however the Tamago's C button screen where your character pop closer to your screen character pixel looks bigger than the Nano.
Jumped from baby to adult
They are alright I guess, you can get your favourite adult characters as soon as possible but maybe they could have added in the toddlers(1 hour after baby), teens(next day) then the adult the next day.
Due the the thickness of the upper screen, it created shadow just below the upper screen(as can be seen on the picture above). Also can be seen on the left or right side(depending on your position).
Words game
With the screen already being small enough. The G and C in the word game looks almost identically the same! I'm not too sure if they are trying to be tricky but it's incredibly hard to notice especially during the close end of the game when every words come down incredibly fast.
