I've released an update to the game, the patch notes are as follows:

>Added a game over screen

>Added text to the progress bar specifying the amount of progress made towards the project

>Fixed upgrade prices not immediately updating

>Fixed the default menu option not being initially highlighted

This is just a fairly small update in response to some feedback we received, though quite frankly I'm not sure how I forgot to make a game over screen. 

The next update that will release (hopefully) sometime soon is planned to be a little larger so look forward to that!
