Challenges lacking explanation

Prey 2006

The first time a player finds this explosive egg there is nothing that tells the player that it is meant to dissolve that organic net. The player doesn't even get a clue that the egg explodes when you shoot it. The player has to find that out by trial and error. After the first time it becomes obvious the purpose of that egg, but the first time is not. That mistake repeats on the whole game. There are many obstacles that the player is left by their selves to solve. There are many objectives that the player isn't told that it is an objective in the first place. If the game tells the player that they must go to a building, it's natural for the player to look for a way to the building. If the game doesn't tell the player what to do nor where to go, how is the player supposed to guess the developer's intentions?
