This program is a Space-Invaders clone that runs on an unexpanded VIC-20
The objective is not to reproduce perfectly the original game, but to propose something very playable and quite fast on the VIC-20. Arcadia has been inspiring, even if the gameplay is very different from Space Invaders.
Compile with "make".
I took some screenshots during the development of the game.
This is the very first screenshots (April 23, 2018). Static aliens, some graphic errors and an Arcadia-style screen size.
Cannon and aliens (April 26, 2018). Movement on aliens. Score is a placeholder, no real code handles that.
Cannon and aliens (April 29, 2018). Aliens move and drop bombs. The cannon can be moved and there are four bunkers.
Cannon and aliens (April 30, 2018). Cannon can fire (rapidly)!
