Terra Cognita

Mining Engineers working on the planet Krion have inadvertently triggered its
destruction, and must escape in this vertically-scrolling shoot ’em up. There
are over 100 screens to fly through, and they include many barriers and narrow
paths, as well as force fields. There are also time-shift fields – some move
you forward, but some send you back to the start.

Enemies are in short supply – the game’s feel resembles Artificial Dreams
(from the same designer). You have limited fuel and must collect fuel tokens
to recharge this. Other available powerups include points bonuses, extra
lives, changes to the constant speed of scrolling, and invincibility from
force fields (although not enemies).
