Objects that obviously should be on the ground are in the sky.
Bilbo routinely goes far above the screen range, even on the first few flights.
None of the objects have an animation or sound when hit. This would make it more visually appealing.
I'd take out the "Inventory" page. Or put something useful in it.
You need a way to get back to the main menu without refreshing the page.
Achievements would be good.
This has a lot of potential but also needs a lot of work.
Fun, reasonably difficult. It lags pretty bad in large rooms with lots of particles. Something to reduce quality for slower computers would be helpful, or even just something to reduce/limit the number of particles on-screen.
I have to agree, it needs hotkeys for the most common actions, *especially* dismissing whichever window is in front.
Perhaps put the tech tree and stats windows into one window. Either way it'll block the play area, but at least that way you don't have to click four times to upgrade each unit.
