This is just an initial view on where some of the features stand, and my opinion at the time. Most of these are not things I expect huge change on. I am simply stating my opinion on the current build so the team can get feedback. All of this is meant as constructive and should not be take as anything but that.
Units
I feel the units themselves are pretty well done. They are varied enough to allow good unit composition, while keeping the gameplay fairly simple. Even at the current build the units looks well done and render nicely. The biggest issue I have found so far is that all the units feel like they are stuck in molasses. By this I mean they move extremely slow. This isn't an issue on smaller maps, but if you get in a huge map it will be excruciating to wait on the units to traverse the area. I don't feel they need a huge buff to speed, but they need something. Scout units do however need a nice speed boost. As a scout they need to be able to explore the map at a decent speed and will use that speed as a way to escape enemy fire. With this in mind it would be good to see them get a healthy boost.
UI
The UI to me is a love/hate relationship. While I like the overall layout, it does need some refinement. I found the unit boxes on the left overlapped some of the buttons when large forces are made. Overall I feel that the unit layout, information, etc. is pretty well done. It gives you the current information on your forces and allows you the option of quickly selecting anything you need to. I like the resource section as it is right now, and the addition of the victory count is a welcomed one. Most RTS games don't really give you the option to see if you are winning or losing at any given point in the game. The research box is one that I feel could be toggled so that you only see it when needed. So far I like the map and feel that it serves the purpose it was meant to. It's a map, so it is kind of hard to screw up.
The building part of the UI is one area I would like to see some improvement. I like the initial direction, but feel it could be refined to allow quicker selection of buildings, units, etc. I would like to see the bottom bar list Structures, Land units, and Air Units. The next up would list for structures would be Resources, Logistics, Factories, and Defenses. For the Land and Air unit options it would show Tier 1, Tier 2, Tier 3 in the second bar. I am not sure if this would help or hurt the ability to quick build units, but it feels cluttered to me right now. It would also be useful to the flow of war if we had a button at the bottom of the screen or attached to the map that allowed instant access to our building queues. Having to go back to factories to build takes us away from the battlefield and if we could call up reinforcements while watching the action I feel it would help the game flow.
The other thing I liked about the building panel is the color of the defensive buildings. I would love to see that theme carried on through each type of building and all the unit tiers. I feel that with the color coordination it gives immediate recognition to the type of building you are going to build and allows new and old players a better understanding of what they are doing.
Gameplay
So far I have to say that the gameplay is enjoyable. Even with the game being very early stage I find it to be fairly engaging to attack, defend, and counter the enemy units. I am very excited to see how the AI will evolve as the development continues. On top of that, it will be very interesting to see how the multiplayer games go. I think the supply line feature is one of the great additions to this game. Once fully realized I think it will go a long way to changed the tide of battles for smart players. It brings a nice since of depth to a large scale RTS game like this.
Research/Unit Progression
Right now the research feels kind of bland. you just plop down 3 research buildings and then click unnamed buttons to get cooler stuff. I honestly don't know what I expected from this, but it just doesn't feel like anything special in the game to me. After playing for a while, I feel like the unit progression through the tiers has a good feel to me. It can be easy to jump ahead and build all the research buildings you need, but without the reactives you are stalled. There could be more done to slow the unit progression so that matches require more effort, but that will evolve as the game gets further into development. With the different tiers of units fighting it out I didn't really notice an extremely over powered unit, but I did find artillery kind of useless for the most part. There range could be buffed some, but I would like to play more and see for sure. I do like that the rocket units, artillery, etc aren't 100% accurate all the time.
Performance
Even on the higher settings I am seeing my performance stay very stable with this build. I'm not seeing anything really killing my frame rate other than zooming out and scrolling across the map. At that point it's kind of expected though. Overall I'd say well done. We will see how future patches and fixes go.
