I was playing the game and realised it's a bit quiet, so I quickly went into BFXR and added a nice ding sound for when you discover a new planet.

When you first load in the sound doesn't play since the no auto play sound rules browsers have now, but should work after that fine.

In future updates I plan to add, well, something to do. Original plan was to have the player be able to shoot "Colony Starter Kits" at the planets for more points, so look forward to that in the future.

I'll probably try to make background music for the game at some point but I'm very bad at music/sound making, so maybe not.
