Very interesting unusual gameplay and cool mechanics.

The difficulty is not too hard but not completely easy, it's very nicely calibrated to always be fun.

The comic page between the levels was nice, I wish it was something different between each level trough, like something warning about new threats in next level instead of in game tutorial. At least the winning end comic page could have been special, but it was the same old.

The game had a nice retro space sci-fi feeling, both graphics and music are well done.
