GASP is one buggy and ugly game; very obnoxious, tedious, boring and the only redeemable quality of that game is semi-decent textures of Mars and Moon

one of the most vile features of that game (not including incredible slow pacing) is the broken achievements. all ten achievements in that game are bugged and obtainable randomly, with, somewhat, unclear patterns

all achievements are available in Mars DLC only. in fact, game is unplayable in main Moon mode - invisible wall just don't allow to finish your mission. so, give yourself a favor and don't play Moon mode ever

game requires you to pay money in order to play in Mars DLC, but you trick game and play that DLC for free. open "select planet" screen and press E button - Mars DLC will be unlocked for you

now, on Mars surface you will see five "Unknown Signal" points in far away distance. in order to get achievements you need to visit each of those points, starting from the most right one and follow to the most left one. the very last "Unknown Signal" you will visit is an "Escape Pod" that will finish your game, that is why we need to visit it last.

you receive

• one achievement when you come closer to Crashing Site (beginning of the level)
  
• two achievements for every "Unknown Signal" you visit
  
• one achievement for the last "Unknown Signal" ("Escape Pod") you visit

now, the hardest part, as was stated above, achievements are bugged.

sometimes you get only one achievement instead of two upon visiting "Unknown Signal" and sometimes "Escape Pod" gives no achievement at all. because of that bugged system you may end up with stats like 8/10 or 7/10. in that case try Moon level and visit all Unknown Signal you can (until invisible wall starts blocking you), then quit the game and start Mars one more time, but try in that time get "Unknown Signal" in a different order (I know, lame...)

yes, your character moves extremely, painfully slow and there is little you can do about it. the only way to make him move faster is to hold the space button to get a maximum
altitude, then releasing the button and make a character drop to the ground - it is about 10% faster compare to just walking. another option to increase speed is to set graphics quality to low, it seems increases character speed a little

about asteroids that fall on your head and Oxygen (O2) level - you cannot die in that game. yes, game stressed that when you die you die, but it is a bland lie. whenever your O2 will hit 0 you will continue the game like nothing happens. same for asteroids - they are just decoration, don't mind to avoid them

was copypasted from my astats guide - http://astats.astats.nl/astats/Steam_Game_Info.php?AppID=412400&SteamID64=76561198967068402
