Defem

In DEFEM you control a little UFO using the mouse, blasting away in all directions.
Although the game is a shooter, you spend most of your time avoiding your enemies, rather than tackling them head on.

Earn points by destroying enemies and collecting gems to create gem-combos. These combos upgrade your ship
with shields, lasers, and more. The higher the gem-combo, the higher the score you get for collecting each gem.

Controls:

Move the ship with your mouse.

P – pause / resume
M – mute
+ / – – increase / reduce music volume
F1 on title screen for HELP.
