Nicely done
Well, the aim isn't that unique (get a complete row of something - been seen in Yoshi's Cookie for example) but the workings of the game are fairly nice, with the aliens making it interesting.
I'd like to be able to blast aliens as someone else suggested, perhaps with another coming along after so long.
The game's all about quickly seeing what can be made into a column and doing it before it gets blasted. But it does lack a bit of strategy.
One thing I'd really like to see (and consider almost mandatory) is a counter of how many more you need to blast. This would make it a lot more user-friendly.
a counter of how many more resets are available would also be good.
It is possible though to find it nearly impossible to complete a level, simply because of luck. Maybe if the aliens had a more recognisable pattern and you could actually use some strategy against them it'd be more interesting.
Still, funky stuff.
