We've made some slight adjustments to the UI in Astra Protocol Remake. Based on player feedback, we've made the UI a little chunkier and brought back the Amstrad CPC style font.

New features we're working on for Astra Protocol Remake includes improvements the routing & pathfinding.
In the original the enemies would fly anywhere.
For Astra Protocol 2 they'd only avoid planets.
Now we're working on them avoiding anything that causes damage.

Introducing the H Ship🚀
We wanted to create something which had an obvious silhouette when viewed on a monitor. What do you think to the design?

New vs Old
A very early WIP for the helm module in The Astra Protocol vs that in Astra Protocol 2
We've removed the compass and incorporated it into the main view. In the space that was left we've added a radar.
Which style looks better?
