Defend Against Invasion from Space

Enter your starship, captain! Numerous aliens are coming to invade our planet earth. You are one of the last battle-ships to defend ourselves!

Dive into "Invasion from Space", a 2D top-down space shooter, similar to the historic space invaders. Defend against wave after wave of alien ships. Every round is generated individually, no fights are the same.

Changelog:

Version 1.3.1:
Fixed an error in which the reported position in the highscore was exactly one better than it actually was (quite annoying, if you're heading for first place - sorry, for the issue!)

Version 1.3.0:
Space ships existing the screen will add 1 HP to the health of your enemies. Every wave passed will add an additional 2 HP to them. Shooting enemy ships will increase your fire power by 1.

Additionally, a bug was fixed which prevented loading the app without a network connection.

Version 1.2.1:
Bugfix: Fixed a bug that caused the points per killed enemy to not being reset after one's own death. (Some lucky people got more points than they deserved ;-)). Thanks for pointing that out!

Version 1.2:
Game rounds become shorter but harder with this update:
- Score per enemy hit is dependent on previous hits and the current wave number (and grow faster than before)
- Difficulty increases faster (fire cool-down, fire rate and enemy missiles change earlier)
- Enemies increase speed after each fired missile

But on the other hand:
- Your score grows faster ;-)

Version 1.1:
- Added a pause-button
- Added a global highscore
- Increasing wave number now reduces cooldown between shots
- Increasing wave number increases damage dealt by player ship

Version 1.0:
- Up to 1.000 waves of alien attackers
- Steadily decreasing weapon cooldown timer
