Basement to the Sky

Today is your birthday. Warm sunshine, perfect weather. Your parents are away for work, but they’ve left you a birthday gift — a rocket. Build your own rocket and launch it high into the sky. Cook delicious meals to fill your stomach, and earn money through part-time jobs to upgrade your rocket. Little by little, higher and farther. How far can your rocket go? Spend a special day that feels like stepping back into your childhood.

Assemble Your Rocket

From the nose cone to the body, fins, fuel, and nozzle, freely combine parts to create your own unique rocket. From water rockets to black powder rockets, solid fuel rockets, and hybrid fuel rockets, experiment with different types and discover the perfect combination.

Launch Your Rocket Into the Sky

Take the bus to an open field and launch the rocket you’ve built. Flight results change completely depending on your design choices. How far will your rocket fly? Aim beyond the sky and challenge yourself to reach space.

The Core of Combustion: Rocket Grains

Each rocket requires different types of grains, which you can craft yourself. Precision is key — if you’re not careful, the results may differ from what you expected.

Earn Money to Upgrade Your Rocket

Upgrading your rocket requires money. Earn income through part-time jobs, stock investments, or even running a video channel. How you make money is entirely up to you. Use your earnings to push your rocket higher and farther.

Home-Cooked Meals Taste the Best

Nothing beats a meal made with your own hands. Studies even suggest that good nutrition has a positive effect on the brain. Cooking and eating meals increases your Knowledge Level, allowing you to choose useful perks that enhance gameplay. You can also share food with neighbors or sell it to earn extra income.
