Today I implemented the upgrade system. You collect credits which can spent at an upgrade store.

The store presents a menu from which one of three upgrades can be chosen. There are three upgrade tracks with two levels each. Each level unlocks a new passive character upgrade. The menu includes a description of the currently-selected upgrade.

I spent the day getting depressurisation working. When the hull gets pierced, the area of the station exposed to space is depressurised. Any characters in that part of the station are pulled towards the breach for several turns until the pressure is equalised.

The red warning light indicates that an area is being depressurised.

Once the pressure equalises, a blue warning light indicates that an area has no air. The oxygen meter will start draining, and when it runs out the health meter will start draining.

I got through a good amount of core gameplay mechanics today including NPCs, projectiles and destructible terrain. I also spent some time focussing on flair, such as special first and last levels, animations in the game menu, death screens, and smoke trails on bullets.

Orbital Decay

You tape over the flashing warning light. An overheating engine is the least of your worries. Gotta focus.

The space station looms ahead. It's out of fuel, and about to come crashing down to Earth. Unless you get to it first. Special delivery: 1 hydrogen fuel cell with enough juice to kick the station out of this pesky atmosphere and back into space where it belongs.
