First thing out of the way- the only thing in this game right now is the campaign mode, the same from the original SS.
It's definitely a work-in-progress. I just popped my old copy of SS in and played it, and then played this version. It's much more touch-friendly for touch devices since it was just released on Google Play (and maybe the App Store?) very recently. This is very evident in the UI. Being able to scale the size of the game would be very helpful, as for having a 1080p monitor I should be able to zoom out far more.
Keeping in mind it's a work-in-progress, here are my observations after having played through the first world of the game:
+ Same great gameplay from the original.
+ The cutscenes are back, as are the original voices. None of that has changed.
+ Campaign now "rates" you out of 3 stars (a la Angry Birds) for your performance. It has no effect on unlocking campaign levels.
+ Textures look much nicer. Not all of them, however (see below)
- Skirmish is not here (but coming, as the developer has announced)
- not optimized for large displays (the icons are huge, perhaps for touch device friendliness?)
- No MP (yet)
- Can't customize controls as far as I've seen so far
- Music has very noticeable looping
- Can't use Build Repeat on buildings
- Too many unnecessary animations in the menus (hiding loading times, perhaps?)
- Textures are updated, which means a very different art style. Others have likened this to looking like "crash dummies" and for some parts I would agree. I personally prefered the older art style because they looked more like off-the-line robots rather than things with personality (which the hero units should have!) but to each their own.
- Units run on the air. Or at least, that's what it looks like. Their feet and shadows don't line up and it looks really odd.
= I would really love it if the developer could also include the nice build animation from the original (or something like it!) because it was really cool to see the lines slowly build and the "walls" slowly form on buildings. It's a much more jarring animation now but is still in stages. A decrease in the animations for "right-clicking" on units would be great, too. It just seems like it makes it take more time than it needs to.
= The menu background graphic is kind of odd- I'm not sure why it's there, as it doesn't really have a lot to do with the game's setting.
= The globe is nice for giving a sense of perspective for where the battles are taking place in the campaign, but it's HUGE. Seeing all the levels/making the transition better would be cool.
= PLEASE try to find a way to bring back the old economy UI! Being able to see your income differential was much better than just having a ticker with how much money you currently have.
Bugs so far- Bunkers having HUGE amounts of health/it not being hit properly; units climbing up cliffs when they should not be able to jump that distance; Units not being able to be hit when standing next to (but not blocked by) a building.
It's also hard sometimes to select certain units in a group. At times units will clump up and then you can't ever select one, it selects all.
That all being said, I still do enjoy the game. Is it as enjoyable as the previous incarnation? Not yet. Hopefully it will be! I'm looking forward to seeing how things turn out. I don't regret purchasing this *yet*, but I'll check back in a couple of months to see how it's progressed.
Recommendation: YES, though be prepared to be disappointed a little, especially if you expect the exact same game with a facelift. The developers are sincerely looking at feedback and that's reassuring.
