despite having a few bugs, and technical issues, this is by far the BEST mining game I have come across in a very long time. however, the above mentioned bugs and technical issues are big enough to not allow for a full 5 stars despite it otherwise very much earning it:
glitches:
1. artifacts are supposed to act as 'elevators' but 80% of the time it does absolutely nothing, only randomly haphazardly sending me upwards, usually when I'm on the surface already.
2: you can't make a recipe for something you already have (ie: first titanium piece I found was normal size, not tiny, I had to break all of it down to tiny, not just enough to make the recipe, before it would show it)
3: items in a recipe list for something you've discovered, won't appear as a question mark, even when you haven't actually discovered that particular item (never mind the fact this was possibly to happen multiple times to begin with)
technical issues:
1: you show where you make recipes at to unlock new items... but then you never elaborate -anywhere- that to actually craft things, you do so from the cargo bay window by selecting the appropriate item. a good half hour was lost solely due to not knowing this.
2: you use an interesting concept of mining around things for various affects (empt lava pockets, open abberrant material, or the opposite, accidently destroy strange goop) which is fine by itself... but then you have an upgrade to reduce the 'amount of vibrations' which causes a problem because it makes it MUCH MUCH harder to empty lava pockets normally, and at max, impossible to correctly open abberrant material. perhaps a way of adjusting it from 0 to current max reduction level?
3: mining gas sources cause explosions... or do they? your only indication that such a thing has happened, is your health drops like a rock... and nothing else. which also apparently does the same amount of % damage no matter how much plating you have. if it's an explosion, why is only you affected? why not clear out surrounding blocks? or at least add a sound affect?
4: the gas explosion causes the same amount of damage to you regardless of plating level. this might be on purpose, but so does heat level, and hitting lava drips all seem to do same amount regardless of plate level... so what's the point of it if EVERYTHING does the same % of damage regardless?
5: your discovering recipe requirements are a little ridiculous... I'm not even joking when I say by the time I FINALLY upgraded drill amount to level 3, not only was it the last one I needed for all subsystems level 3, but 7 of the 12 were already at the max of 5, not because of needing more materials, but simply because I hadn't 'discovered' the necesary recipes yet... this was especially frustrating when I needed to upgrade cooling to get to what I needed... but couldn't because I needed to find artifacts that were lower then I technically should have been going.
