Really nifty little game; with some UI polish it could really get going.
* Health usually counts down; you could make that bar a Damage bar, which would naturally make you blow up when full.
* I like how New York and Paris are cities, as well as California ;) (maybe San Francisco could work).
* I wasn't fully clear what money was used for at first; I know the info's right there, but it didn't grab my attention at first; again, some UI tweaks there.
* Also, feedback on how cities will/won't react to your threats could be cool (a la Civ), but that's just a bonus.

Thanks for your feedback! The UI does need a major overall as its a crucial element. We plan to give more player information like you mentioned for sure.

The viewpoint of the game is new, and the orbital scenery is fantastic, but I hope the game mechanics can be more clearer (for a strategy game) :) It like after I build certain notority through obliterate a small city and get some ransom, I can just walk around asking for money without doing anything else.

You seem to be able to play on even after you die. Fiendish!
Great idea though.

I had trouble with the UI, while obvious didn't seam elegant, otherwise a nice game, I wish it had way more weapons and way more cities

Finally,, a world-domination-simulator other than my own!

Needless to say I love the idea :D. The space-station view is great, and the music adds a nice eerie feel.

Very cool presentation and interpretation of the theme. Would have liked to have a better idea of what my goals were and how I was doing. But pretty cool overall, nice moody music too!

I don't understand the complete gameplay, because after shooting one, i can threat in loop. and have infinite money and shoot what i want. But i like the visual :) (i think i will like all the game where you see our world from space)

there was a really nice ominous mood to this. i liked it.

Cool game, I got impatient when they all paid so I vaporized them anyway! :D

Nice one, amazing innovative, bit confusing GUI but very nice idea and execution.

Pretty game with great music, I felt so evil! But I couldn't launch missiles on cities :-(

Nice overall idea! With some more polish and UI it could be a really awesome game :)

Thanks for the feedback so far. @Yakka - Only an Anti-Missile weapon so far which is enabled when cities fire missiles at you. Don't worry you'll be able to drop the bombs very soon.

UI was just a place holder, hopefully something better soon.

Very nice simulation. Graphics are awesome ! Well done

Great work! It's a very satisfying feeling to be orbiting the Earth and holding powerful weapons pointed at the surface ;) There didn't seem to be a lot of warning as to when cities would retaliate - or pre-emptive strike, maybe? - but it's a very good entry.

Nice entry!
It was a bit confusing though, and the mix between mouse controls (UI) and keyboard is not exactly optimal.

A piece of advice: When your game requires both hands to be on the keyboard (e.g: using directional keys to move and F/C as fire and camera buttons) you can't expect the player to also use the mouse. We only have two hands and switching the right hand between keyboard and mouse is not efficient for a game.
That's why FPS games corner all the keyboard controls in the left side of the keyboard, so you only need the left hand on the keyboard, leaving the right hand free for mouse action. Yes, it doesn't account for left-handed people but it shows how to properly implement keyboard+mouse controls (keyboard can be used with just one hand while the other is in the mouse). You can solve the left-handed issue by mapping the keyboard actions to keys on the right-side of the keyboard as well.
Graphics are fairly decent (some are great) and music is certainly quite "villanous".

Well, congratulations on your first jam game. It's -despite its minor flaws- a nice and challenging game! :)
