SharpSCII Invaders

This is a simple one-button game where invaders from outer space are attacking planet Earth. You are humanity's last hope!

The aliens attack in waves, and have to be shot down before they reach the bottom of the screen.

Features:

• Monochrome graphics made entirely using SharpSCII characters – some of it has even been created on a real Sharp MZ-80A microcomputer!
• Sound effects and beepy music programmed in BASIC SA-5510 and recorded using an emulator!
• Silly cutscenes!
• Jokes and jumpscares!
• 20-ish repetitive levels!
• Procedurally generated background graphics!
• Very well hidden Cheat function!
• Lots and lots of green!
• Undocumented mouse control (left button)!

The game was mostly created as a learning excercise, to prepare myself for converting Numbertron from the Sharp MZ to the PC. It's free, but feel free to check out Numbertron if you want to support me.

For those who don't know, SharpSCII refers to the character sets for the Sharp MZ range of Japanese microcomputers from the late seventies and early eighties. This game uses the characters from the European Font ROM of the Sharp MZ-80A.

The Sharp MZ-80A looks like this, so it's pretty cool:

This game is for Windows, though. :)
