Interceptor Demo update 2023-07-16

Update 2023-07-16:

• Added a final score screen that tallies up kills by a craft type.
• Instead of looping back to the start of the spawn list, level now ends in victory if end of spawn list is reached and has a special splash screen to inform you of this.
• Minor tweaks to spawn list.
• Level splash screen is skipped after the first attempt at a level.
• Energy Bomb recharges slower (roughly half speed) while main guns are recharging.
• Fixed a bug where the secondary palette was getting reset on Super Game Boy, causing bullets to have one of their colors to match the background color, making them harder to see.
• Explosions now use the same palette that bullets do in non-Game Boy Color modes.
• Game over screens updated for clarification on what B and Start do respectively.
