How to Play Mirai Shinwa Jarvas
Quick start
For the title, select the item with SELECT and confirm with START. From the starting point, go northeast along the road and aim for Buruga Town. First, go to the guild and choose a job such as swordsman. If you open the strategy screen with SELECT and set "Botan" to "Command", you can talk and explore from B. Use ``talk'' after making contact with the person you are speaking to. In the early stages, it's a good idea not to easily ask for ``skull bana'' at the job shop, but to sell ``pots'' that can be collected nearby to generate funds for equipment and medicine. To save, click "End" on the strategy screen. Check your physical strength and return route before overwriting.
Controls
Cross button on main screen: Move up/down/left/right. A: Attack. B: Use the command or item selected on the strategy screen. SELECT: Strategy screen. START: Switch pose. On the horizontal battle/castle/cave screen, move with left and right, jump with up, and attack with A. On the strategy/strength screen, press the cross button to select, press A to confirm, and press B to go back one step. The purpose of B can be changed using the button on the strategy screen.
Mirai Shinwa Jarvas — About this game
The protagonist returns to Earth on the space probe Gervase and searches for a way to survive in a world where the civilization of the past has been lost. It's an RPG where you walk through a top-down field, collect information and equipment in a town, and fight in a castle or cave on an action screen seen from the side. You can't earn money just by defeating enemies, so you need to raise money by delivering goods to work shops. Grow by using the guilds of swordsmen, fighters, and magicians, and as you gain fame in matches, you can gather friends. To attack a castle, not only the strength of the protagonist himself but also the strength of his army is important. Gather information about the handprints you pass through checkpoints and each location, and steadily expand the range you can go to. You can save your progress, but if you save without checking your way back or your health, it will make future exploration difficult, so use caution.
