  The amount of Controller hits is separate for each level. Upon achieving zero hits, the Controller does not become neutral yet, but its level decreases by 1. Hence, complete destruction of a 8 level Controller requires 8 times more time than complete destruction of 1 level Controller. Soon the amount of hits per level will be slightly reduced, follow the changelogs.

  Oh dear. I actually, even after copy/pasting it into here, failed to realize i left role: 'x' in there. Meant to change that to harvesters. Thanks for your help, it finally works. I checked the memory, I had over 202 creeps spawn since I started it, which was hours ago and even running on 500% speed, it was still taking between 5-10 seconds per tick. There were easily over 100 creeps on screen. SO. MANY. HARVESTERS.

  CPU Usage Optimizations?

  I messed around with using c++ with emscripten, and it produced javascript files that were 800kb or so (300 when minified). It would frequently spend about 100 cpu just loading the script (without calling any functions at all), but I did not notice any difference minified vs not (there might've been though). It seems like they're using V8 javascript engine, since performance is similar to node.js and Chrome, and there is definitely no support for asm.js. It seems to me like there is significant overhead with functions being constantly recompiled. I worry that by the time the JIT gets warmed up the tick is already over and it all gets recompiled the next tick. Right now I'm using LLJS and using ArrayBuffers for some stuff. The performance is good but there is significant overhead with serializing data into Memory because it is converted to json for storage and ArrayBuffer is not supported, and converting to utf8 string is expensive. I would be quite happy if Memory supported ArrayBuffer. Honestly I think they could improve the "caching" of scripts or otherwise let the JIT keep compiled functions between ticks, but it's possible their infrastructure prevents this. Or they might already do it and I'm reading things wrong, it's hard to profile code running on their servers.

  According to this changelog: Breaking change: All constants removed from the deprecated Game scope. Now they are accessible only through the global scope. You have to amend your code like this: var bodyExtractor = [CARRY, MOVE, WORK, WORK, WORK]; Game.spawns.Spawn1.createCreep(bodyExtractor, null, {role: "harvester", set: "extractor"});

  From this news post: Our Indiegogo crowdfunding campaign funders have already been granted access codes and can start playing right away. If you don't have the code yet, don't despair. We watch the situation and server load, and as soon as our infrastructure is ready for more players, we'll start sending out codes to those who have submitted requests. It may happen even in a couple of days. If you have not submitted for your code, you can always do it here.

  Paid CPU resources will be available after the Early Preview stage is finished. However, 300 CPU is the maximum available capacity to purchase.

  Breaking change: Exit objects removed from the game. Now all non-wall border squares (i.e. with x or y equal to 0 or 49) are treated as exits.

  It's around alpha status, so I wouldn't expect anything to stay stable. The private Early Preview stage starts on May 20. Breaking changes are noted in the changelogs, so keeping tabs on those are a good idea. In addition to getUsedCpu, the update before that removed Exit, removed some deprecated functions, and the constants on the Game object.

  You may be able to do: Memory.roles.foo[0] = function(){}.toSource() Curious though, why do you want to do that? It takes more space and doesn't really convey any real info.
