I got a single-player test run in, and am very impressed at the foundation here!
1) The nice retro 8-bit/pixelized look of the core is fantastic. On all units, really, but the core was just all around impressive. :-)
2) I like that the resources require doing more than turtling in and building up to be effective--you have to engage.
3) The fact you've got this done in just a couple weeks is massively impressive in and of itself.
As for suggestive feedback... I would love to see the overall game speed cranked up about... oh 50-75% maybe? Right now it's seems you're going more for what I consider a micro RTS (meaning the battles are small scale with a focus on individual units--think Command & Conquer), versus a macro RTS (where it's more focusing on a large scale, and you're sending mobs of units and just concerned about army movements as a whole--a la Supreme Commander). This is completely personal preference, but I think micro RTS need to be faster paced to really get a firm footing in the intense, small scale battles where each unit matters and you have to react **NOW** to win.
