What a sneaky trip to Mars!
Game play is interesting. I thought there were only four tasks to complete, but one had to get a medical kit before the boy could go to sleep. Clues for unlocking that cupboard were scattered everywhere on the ground level. I tried two full words I found in rooms and they didn't work. Then, I realised I missed out subtle, yet, noticeable colour changes in other words. Finally, I could go to sleep.
