My Final Score was 69...

more space for building is needed

very, very good!

I would recommend another ressource than "diamond" in the quest, maybe something that is essential for space traveling.

I would add endless mode after the last singleplayer level, or use that ressource (currently diamonds) mentioned in the story to proceed to another planet.

grammar error after finishing last level: "We are now living the planet." should be "leaving", not "living".

Keep it up, liked it a lot :)

Gameplay:
The game length is neither too short nor too long, took me about 1 hour to complete the campaign. At first, I was startled by how slow the research units are coming by, but I also noticed that the base has a pretty good defense, enabling it to be left unrepaired for almost half of the game. The game could be made longer, or add in an endless mode.

I am disappointed by the upgrade system, as I am more into having lots of turrets in a defense game. The requirements for each turret and the limited building space also makes it so that the player cannot have all the structures exist at the same time. However, as the game is very short, the devs must have limited the upgrades to act as sort of a balancing mechanic.

The random incoming of meteors acting as obstacles and the limited aiming area adds quite a nice bit of challenge to make the game seem more fun.

Graphics:
Nice variety of enemy graphics, although the only difference between them are attack value, the amount of health and how fast they move. The meteors and other background graphics are less than mediocre but can be ignored due to good gameplay.

Others:
Music sounds good, fits the environment.

The story is acceptable, but sometimes the wording or the story itself just does not make sense, especially towards the end of the game.

Overall, not a bad game to waste some time on.

A wanna-be mix of Hold your point with upgrade status... I don't like this kind of game, also the quality is changing all the time and it's almost impossible to play it
