How to Play Hamster Paradise: Pure Heart
Quick start
Select "From the beginning" on the title screen and follow the instructions to set up the owner and hamster. Start by feeding your pet in the cage and continue caring for them by petting them, playing with toys, and cleaning them. Once you've made friends, talk to your friends in Hamtown and use the shop to advance events. In the dream town that the hamster goes to when he sleeps, you can solve the problems of the animals, and as you discover new species, the number of facilities and mini-games increases.
Controls
Cross button: Select conversation options, menus, items and objects to take care of. A: Make a decision, send a conversation, perform a selected caring or investigating action. B: Cancel/Return to previous screen. The 13 types of mini-games have different operations for each event, so please check the rules displayed before starting. In the GBA version materials that were available for viewing, it was not possible to confirm the common assignment of L, R, SELECT, and START, so unconfirmed functions are not listed.
