I adore the design and visual presentation here. It's a significant departure from the stock-standard fantasy dungeon which makes an immediate impression. You have a great command of designing the UI and it wouldn't be out of place on any top-tier game of the DOS era. After a little bit of tinkering with the systems on offer, everything makes sense where it is and remains very informative and accessible. The spritework is excellent and reminds me a little bit of Space Station 13 for some reason; maybe it's the sci-fi theme. I also appreciate there's a little bit of environmental design, with signs pointing the way to special settings in the mine.
The gameplay is good too! I enjoyed exploring the Martian mines and exploring the depths to collect resources. Adding dialogue logs invests the player in a little personality and guidance. The sheer amount of systems here is impressive and all thoughtfully executed: there's a survival-style oxygen management, combat with adjustable weapons, resource management to collect equippable upgrades...yeah, this all clicks together excellently. I'd say to myself, I wish there was a map, press M and lo and behold, the map zooms out. The forethought and design behind this one is really obvious.
I don't have any constructive feedback for this one - it's very accomplished and I enjoyed exploring the world, which is an inordinately difficult thing to do for a roguelike style game.
