I was able to finish your game) There are some troubles I encountered. Puzzle do not work properly, It shows that it would be only 3 colors but it doen't reset color up to 8. But... You can walk through the wall and some doors to the bridge through the door and through the wall with near engine. Gun should be pointed to the low point of the creatures to shoot. Overall this is a funny game I was positively surprised that there is a outside location on a planet. Art is consistent, maybe portrait is too realistic for the setting.
