Update #9 - Significant Balance Patch + WASD Movement — Deep Space Cache Steam update #1354619

Changes include: - Complete overhaul of the skill tree progression numbers effectively fixing the slow early game and making it easier to reach the end game with consecutive unlocks being lower. The final unlocks cost almost half as much as before. It still requires quite a few amount of bits but due to the easier access to the late game unlocks, it should effectively make reaching that point easier. - Reduced the cost of the bit mine purchases by a significant margin. - Reduced the frequency of smaller asteroids which should remove most asteroids that are difficult to shoot and aim at. - Added WASD movement. - Added an auto-shoot toggle button. This update and the last update should fix any balancing issues players might experience.
