Not bad, but you need to expand it past a nearly exact copy of something else. You did all the work to code it, you might as well put some new stuff in there and see if it works out.
It would also be cool if the game remembered your bridges so that you could switch levels and come back.
Here's my strategy (figured it out on Level 5): Use a distributed attack. Grab the tiny ones ASAP, and as you get new nodes, use ALL of them (you can select multiple by dragging a box) and attack things. You'll lose some stuff but if you're very aggressive with the smaller grays you will do good. Let the computer attack the higher-value neutrals to even out the battle even more. Once you have about half the nodes, start taking down the larger ones. You should have most of your nanos out attacking at all times. If they're sitting in your nodes, they are not earning you new nodes.
Yes this strategy will be very laggy =)
This would be more fun if there was some actual "game" to it. There is very little that you actually do. Neat concept, boring execution. Not to mention that the only way to win is pure chance, as far as I can tell.
I like that it just says "Game" when you lose.
The basic gameplay is not bad. You might want to make mouse control an option, and I would change the background from blue if you are going to have blue enemies moving around.
I played through twice, and the first time I went for mostly shields (like 2:1 with guns) and I couldn't dodge the final boss so I started over and went for 30 speed, 75 shield, and the rest guns.
That worked. Just get lots of shields first so you can live, then get your speed up with your guns. Once you get 20+ speed you can just move and shoot behind you and kill 90% of a level in the first few seconds.
You're.
The style of movement is interesting when you are engaging an enemy but very tedious when you just need to cross a long area... so many clicks!
Sometimes after you die, you immediately die again because you can't get to where you need to quick enough. Other than that I made it a ways into the level (game?) and seemed as synchronized as any flash game can be.
Definitely run into too many times where the middle ring is missing the right color -- 7 times in one game for me.
Hotkeys for the rings (1234 maybe? or asdf?) would be good, and overall the game needs something else, since within 3 seconds you've done everything the game will ever want you to do. It doesn't get harder as you go along -- you just run out of time.
