@Cythera in the first mine where i battled something to get access to it, level 2 has a place in the wall where i can go through and walk all over the black area, there is also one in level 1 or level 3 sorry i forgot.
i suggest u to make the game longer and add alien pets,rpg battling,searching for people,befriending aliens and story choices.
EDIT: also rpg movement and pod house upgrading and rather than escaping u make your life easier and also probably start technology and soon spaceship to travel to...
A very good game but it needs:
the other characters following behind u
a main area where u have to go many times and it has a tavern where there r many NPC's that give u hints about what to do in some places/situations
needs more buildings and NPC's
and one more character in your team.
