Super Space Invader is an action-packed arcade shooter created in under 48 hours for the programming contest Ludum Dare.
Super Space Invader combines space invaders, bullet hell, some Vlambeer, and other influences. You can plow through 13 waves, choosing from 13 ship upgrades after completing each one, or skip straight to the last (infinite) wave with a fully upgraded ship in sandbox mode.
Keeping with the theme of two-button controls, there are only two buttons: left and right. Hold both together to confirm menu item selection (or just press enter if that's proving difficult). Tap both together to toggle the shield (available after a couple of waves).
