Thanks for playing our game and for your feedback! Glad you enjoyed it!
There is actually an indicator in terms of the color of the spaceship itself. However it was one of the things that we wanted to improve but couldn't because of the time. Thanks again for your feedback!
Ah, really sorry about that. We checked for colorblindness compatibility yesterday morning, but after that we had such a flurry of UX improvements and sounds that we forgot to check again!
