Portal Buster
shoot'em up game for Commodore 64, 2024

------------------------------------------------------------------------------
A fast-paced bidirectional horizontal shooter – and perhaps too fast for some
of the armchair scroller fans, but what do I care, I need speed.
To sweeten the deal, you get infinite continues, nine levels of weapon
power-up, built-in trainer modes, portals and respawn points. So battle your
way through a gigantic 32k pixel-wide level to find and destroy the end
boss.
You need to pick up fuel barrels to keep your spaceship afloat. If you
activate both sides of a colour-coded portal, you can reap the benefits of
hyperspace and travel instantaneously. Doors require buttons to be pressed.
Key mapping:
Space : Pause
M : Music on/off
H : Half-speed trainer
I : Invulnerability trainer
O : Overtime
