I don't know if you know this, but upgrading towers is free, once you have enough money, you don't lose it when upgrading.

oops, you're right. Thanks for noticing.
I hope it's okay that I pushed out a small bug fix for this.

I liked The Space Game so I liked your minimalist version :)

Nice game, but it takes way too long before the first enemy shows up. I thought the game was broken.

Nice game, works perfectly.

Very fun!

I'm not even sure if upgrading was a needed mechanic.

I couldnt understand if the quanity of harvesters effected the income rate, or if it was the area covered that effected the income rate though.

Nice job!

Nice minimalistic mechanic. My top score was 5270.

I like tower defense! This game kept me going for a while until I was invaded by a huge horde of orange circles. Very fun game.

I get my ass kicked :)

Got a slightly better score 7250. I wonder if with the right balance of harvesters/cannons and upgrades it's possible to continue indefinitely.

Nice and simple, good use of the theme! It feels a bit too easy though and it could be a bit faster paced.

Is there a keyboard combo for zoom in an out (seeing as scroll wheel is dead on HTML5 version)?

Surprisingly addictive, gets really hard really fast though (for me anyway!)

Yeah pretty addictive. Only thing that bothers me, is having to click on the right panel for every building. Cant build fast enough. :D

Cool game though it gets hard fast.

Thanks for playing and thank you for your nice comments. I'm glad the game is enjoyable despite the balance and pacing issues :)

josefnpat: You're right that upgrading doesn't do much for the game currently. I probably should have left that mechanic out of the compo version. And the area itself doesn't affect income, this should have been made clearer.
mrspeaker: You can also zoom with pageUp/pageDown keyboard buttons.
xDreamCoding: It had originally made it so you could build repeatedly until you made a right click. But right-click doesn't work in html5-edition, so I changed it in the last minute.

This is pretty solid! One of my favourite LD entries thus far.

*Damn you, orange circles!"

Nice game. Its a good idea making the canons use energy. In most rts-games towers/units have a magically infinite ammo-source:D

Nice game, addictive, but little too slow.

Nice entry! I was doing very well until this happened: http://img824.imageshack.us/img824/2351/minicirclewarsgooglechr.png. A bit too much for my defenses ;)

Nice game, although you really should make the cannons aim more intelligently (taking the target's velocity into account) so that they do not miss that often.
