Play the tutorial for further information!

The key is to focus on staying alive rather than to prevent the enemies invading your orbit. Your ship has only 3 lives, while your orbit can easily be repared after each wave.

Quite good

Very fun game, once you get the hang of it. I like the simple ship style and the bright colours. Very hard but if it wasn't challenging it would be boring. Building walls and turrets is a great idea. It would be great if you added a "Return to Main Menu" button somewhere in-game. (If there is one, I didn't see it). Fun but challenging.

Great game, but has one critical bug.

Pretty darn good, but it's got some issues. I too experienced the bug where the bullets all get mashed down to go no further than your buildings, and the game grinds to a halt. For me, this happend twice on level 30.

My strategy is to build two overlapping layers of turrets all the way across, and put reflective walls all the way across at the very highest row. I don't even have to shoot at that point, and just buy upgrades or maintain my walls.

It would be really nice if we could SELL turrets and buildings, so we can recoup some of our investment. If you do another versioin maybe? :)

Nice game, though lagged at level 23

I had a lot of fun, but at Level 23, the game suddenly began to lag as I added my 16th turret. Suddenly, all the shots bunched up into a solid line that did not go much further than my buildings, and everything slowed to a snail's pace. I eventually had to close the window. I tried this a few times, and it happens around the same part of the game. Perhaps a problem with handling too many graphic elements?

I did like the game quite a bit other than that.

Very good

I sucked at this the first time and read the disparaging comments and stopped playing. But then I thought it was worth another shot and played again and found that it just takes a little strategy. The planet repairs are cheap, so it is best to let things through rather than get yourself hit. I ended up laying out the cheap turrets on top of eachother so they hit every column except the edges, and put semipermiable walls on top of them. That way I could just sit back and watch. It worked well until about level 22 I think.
