After Trijam #87 fixes

Fixes and improvements that we made with @alekzs:

• Added trail renderer to spicy up gameplay and add visual candy
• Fixing Score calculation (thanks to SpatiumSpace for noticing this on our twitch stream)
• Using Custom high score service and going away from dreamlo.com (as itch.io doesn't allow HTTP requests)
• Fixing that planet's that are not placed cannot effect players movement (because you could exploit that)
