More updates in this early release 006:

• The background for level 1 is completely reworked to better fit the game, there's some early parallax scrolling in there too (not entirely satisfied yet, but looks better than the previous background)
• While playing, pressing escape now displays a menu instead of immediately quitting
• The player ship has a shadow in level 2 now as well as in level 3
• New boot splash screen (often invisible because the game loads so fast)
• Some improved explosions

Known issues

• Level 3 is unfinished
• When restarting a level, some bullets can still be flying around, will be fixed in another update.
