Been playing this for a few hours over the last couple of days, and it's pretty rad. I dig the constant progression aspects of it, and the single mission stuff is great to launch into if you've only got time for a ten-minute playsession. I'm still not great at it - figuring out precisely how to set up stuff like go codes is a little complicated, and I generally tend to just stick with real-time mode and cautiously move guys around rather than create elaborate plans in the strategic mode. Maybe I'll give that a whirl, though.
Seems like there's a decent amount of content for 20 bucks, and the level editor looks like it'll allow for a bunch more to come down the pipe.
Hope this game catches on! It's a great laptop game, too, as it runs even on my old-ass Dell at work. I'm sure a tablet version is in the pipes, but they'll have to make some changes to the control scheme to make that work. My main criticism now is that it could probably use a more amped-up soundtrack than what they went with, but maybe that's just the shadow that Hotline: Miami casts over the entire top-down action genre at this point.
Also, I guess I should note that it's remarkable how quickly this game launches and exits and loads levels. It's obviously not rendering megatextures or anything, but you can literally go from hitting the Steam launch button to being in a single mission within ten seconds. It's entirely conceivable that you could get a whole mission off before your boss gets back from his bathroom break. An under-noticed but really appreciable thing in these times of 45-second pre-menu splash graphics. (This is one reason I gave up on Metro: Last Light.)
