Thank you for playing my game! I'll definitely take a look at that bug as soon as possible. however I just have a few notes:
1. yes it is a bit like ZORK, that was the original inspiration for the game
2. the reason my main options are listed with numbers is because I myself began playing ZORK and found it very difficult to play without knowing a whole lot about what i could do
Overall thanks for your feedback! A fix for that bug will likely come out with the next update, however as i mentioned on the games page, you may need to wipe the save files in the first few updates, that will be fixed in the near future
