V2

• General fixes, e.g. fixed trapdoor ball respawns, removed possibility of death while the boss is exploding
• Slight graphics tweaks, e.g. new dot matrix animation, shadows for things, no more random gap between slingshots on boss stages
• Second zone "Graveyard" added, follows from first "Tech Zone" immediately in Arcade Mode
• Stage cleared screens for a breather and for player information
• Balancing of Upgrade Shop, prices creep up as you make progress
