Re: germohile's comment: This game refuses to render if you're using Firefox. At this time, one wanting to play this game in a browser on a Windows PC needs to access it using something like Chrome or Vivaldi.
Hopefully, the developers get with the program and fix this issue ASAP...
BUG(S) REPORT (a.k.a. inadvertent causality loop): When the user researches engine capability to approach c (i.e., 669600000 mph) before installing all purchased engine upgrades, returns to the launch planet, and relaunches the ship, the ship fails to stop at any planet regardless of degree of mission completion. Other issues (likely reported previously) include failure of game stats to display total gold earned (0) or research projects completed (0). Fun while it lasted, though.
