V0.4

What's new in V0.4?

• Use custom font provided by 0x72 in this assets in place of the cc65 lynx font. The code was based on Igor's 7 segment font demo (https://github.com/ikromin/atarilynx/tree/master/demo/7segmentfont)
• Refresh title and end screen with image to have a custom font. 0x72 don't provide alpha charset so that's my own work, I hope it was readable.
• Add sound effect on explosions. It was a little hacky usage of Chipper, I hope it works on real hardware.
• Add hi-score to the end screen

If somone can tell me if the game works well on real harware I'm interested. :)
