Having to use control key to slow and W at the same time can cause some issues on web games haha. Appart from that I can see the hard work on this, I am very impresed that you managed to get all of this done in just a week, even with multiple endings!
The art is very good, loved the UI and the effects/shaders and also the movement of the ship felt very well done. I played all the endings just because I was so immersed in the story and wanted to see what was going to happen. Really good game!
