Firstly, thank you for playing our game!
The controls are stated on the Game Page as well as the video trailer on the same page. As for the art style, we tried to keep a consistent pixel sprite style between the art team. There are different themes - steampunk, dieselpunk, and cyberpunk - to simulate different time zones in advancing worlds. In terms of the game closing when you lose, it is something we have all said we will take into consideration on how to fix this for our next project.
However, I'm glad you enjoyed playing the game!
