How to Play Nakayoshi Pet Advance Series 1: Kawaii Hamusutaa
Quick start
Start with the initial breeding data from the title, select one hamster and name it. Please check the first test given by Hamrietta and use up the 16 scales for one day by selecting feeding, cleaning the toilet, playing with toys, etc. from the menu in the cage. Friendship points will increase with each action, and if you repeat the same care, the number of points required will decrease. In the early stages, it is safe to avoid buying too many tools and prepare for the next test by saving money and collecting tools of a specific color.
Controls
Use the cross keys to select menu items and tools, press A to confirm, and press B to cancel/return to the previous screen. In cage display, you can rotate the viewpoint using L/R. The unique functions of START and SELECT are not listed as there is no documentation to confirm them. Basic operations are centered on the screen menu, and selecting a care will consume the corresponding scale and the remaining time of the day.
