ld48 - Jupiter drop

You're an eccentric explorer diving into the depths of Jupiter with a bathysphere to discover what is at its core. You must balance energy requirements, risk hazards, upgrade your bathysphere with money you make from selling science and mined elements.

Game features

x Can see your ship and bathysphere descending on screen via a depth gauge x Can see what layer you're at based on depth x Can see outside temperature as you descend x Can see pressure as you descend x Can see power as you descend in kilowatt hours x Can see hull health as you descend x If hull health reaches zero it implodes and you die x You can sell excess hydrogen x Ship power is refueled via hydrogen you capture, fusion reactor x If you run out of power you die x add self destruct x Can vary the speed of descent with down arrow ( velocity ) x make dropship bigger, you basically park in it x If internal temp gets too high you die x Your ship dissipates heat at a controlled amount can see internal temperature x Can see a diagram of our bathysphere in between drops and click on parts to upgrade x Can equip bigger sample tanks to catch elements, but they slow you down

• Sinking too fast or using more power slowed down air conditioning
• lightning knocks out power
• Can reroute power to devices (air-conditioning, speed)
• Can upgrade air-conditioning
• can upgrade hull strength
• can upgrade descent speed
• as you make discoveries / science, opens up new components to purchase
• You can see the different layers change visually as you get further
• Elements are displayed as big clouds
• Can equip minor steering to sway in the direction of clouds
• Reaching new depths unlocks science that makes you money
• can buy radar to steer towards elements and interesting objects x ship has an inventory you can store and swap out bathysphere components
• can equip special hull layers that are consumable
• metallic hydrogen is very valuable
• metallic hydrogen overpowers the ship, must dissipate energy fast
• can see an atmosphereic wake as it descends
• can see a overhead scale of the atmosphere
• flash "out of power"
• can see power demand as power icons
