Thanks a lot for taking your time to playtest the game! I have opened an issue to address some of the points you brought up / ran into. https://github.com/benkeks/dgx9142/issues/3
(I'm very pleased to see that the game can at all be started without serious bugs. I mean this is basically 10 year old software compiled with an experimental updated version of a 18 year old compiler, which, by the way, also is responsible for the missing input of capital letters.)
