Allow movement of multiple aliens at once (or at least allow them to be clicked and aimed when others are moving) and You have decent game.
currently it's more like wait till that guy hits end of road and try to aim as fast as possible.

The game is actually funny, have nice graphics, but the controls are a lilttle hard when you don't have too much time to think and play. I mean, you gotta be so fast to click in all the ships and throw them to the right place, that's uber hard when you got to do it as fast as possible, running agains the few seconds you have, and thing about what are you going to do at the same time.

A deep plot isn't needed. but a little more explanation as to why the alien's want to hover over these colored rocks would be nice. And also, I feel like the timing is a little too harsh for the controls to be so rigid. There were many times where I knew exactly what I was supposed to be but the game wouldn't let me click fast enough. Considering making it possible to have two ships moving at the same time (one after the other).

i dont like these type of games but it seems good so 8/10 4/5
