It took a while to understand a purpose of the game and a fact that not all commands are available immediatetly. Some of them to be unlocked. Maybe a turorial would help a lot. Also the battery drained too fast. I hardly did anything and then I'm out. Last time I used command to buy a battery - it said I did it, but still nothing changed and 3 secs later "game over".
But still the game is cool and innovative for me! Thanks!
