Hi Sebastian,
Just played one and a half levels of Goldspace.
What can I say - a wonderful experience!
I loved:
- Automatic actions (hacking, lockpicking etc)
- Destructible environment
- Artwork
- Animations
- Music
- Dialogues
- Easter eggs (nod to Doom

What I thought could be tweaked (only minor points so far)
- Navigating the Main Menu with arrows (in addition to WASD).
- Use Esc to get back to the root screen of the main menu.
- Maybe show controls after start of a new game, not before the main menu? It's very easy to skip the splash screen, then I explore the menu and clean forget what I saw just before it.
- The Credits screen is illegible due to overlapping text strings.
- Maybe don't reset the main music theme when I get back to the root of the main menu from a submenu.
- When the Shop window is open, use Esc to close the shop window first (not open the main menu), or add a big on-screen button for closing the shop window, which could be selected by arrows. I saw a red cross in the top right corner but I couldn't figure out how to press it.
- Separate the icon of the weapon from the life bar by more space or a vertical line of sorts. Otherwise (especially with the green colour of the health bar) it looks like charge level of the weapon. Or at least maybe make the health bar orange?
- Enemy AI: I noticed the guards simply follow a direct line to the player, which means they'll hit the wall and start to slowly slide against it (which means I can safely kill them while they are moving from around the corner). Do you have issues implementing the AI Tools extension? It has a choice of pathfinding algorithms that create a hashmap with tile coordinates for an actor to follow. I used it in a scrapped RPG prototype and it worked fine.
Anyways, Goldspace is an amazing game with a great vibe, which I want to play more in my spare time!
Are you setting up a Steam Early Access page any time soon? The project's at a very mature stage...
