Some tricky puzzles in there, for sure, but nothing that was too terribly taxing. Beat it in an hour without too terribly much difficulty. However, I frickin' LOVE these games. Just my kind of puzzles. Giving it 5/5 to be generous, though I would really like to see a toolbox to keep the pieces out of the way, separate sound and music mutes, and maybe a fast button?
Altimeter would be nice, for tracking progress, as would maybe counters for fuel, money, and repair pickups, and gates passed through. It's also incredibly hard to make it through a gate without taking damage from the gate itself.
Beautiful art. Music sets the mood nicely, which is reinforced by the writing style in the dialog and story. Slow, peaceful, sad.
Just fix that scrolling bug, and we're good to go.
After getting the best fighter and fully upgrading the frag shots, you can beat every single level buy just sitting centered at the bottom of the screen.
In the description of the rotating tool, "locating" should be "located." Also, it doesn't really make it clear how it flips it. The design of the piece itself makes it look like it's going to swap what's above and below it.
It'd be nice if it had an ending of some form. Best I can tell, there's nothing to do after you've upgraded everything but fight through wave after wave of zombies, which gets old in relativelly short order.
Fun while it lasted, though.
Great concept, pretty well executed, some nice puzzles, on the whole, though, I found it very easy. (Thanks to updates rolling back some of the levels I'd previously completed, without taking away any starts, I'm up to 102, haha. :D
