Howdy Screeps team!
I love the idea you have going on here and think your UX is great considering all the complexity behind the scenes. You deserve to hear my first impressions before I quit playing.
I got to rank 90 of about 140 players over the past week and had a blast doing it. Thanks for the free Twitter credits! I hope you'll contact me if something changes to let all players equally use the same amount of CPU each day. You certainly deserve to be rewarded financially for bringing this great game to life, however, some of my friends refused to even try it out knowing they would eventually have to pay money for accidentally writing infinite loops.
Maybe you could use Kickstarter to fund it? It would be cool if Google or Facebook purchases this game to use as a recruiting tool or something because as fun as it is writing and learning JavaScript in a game environment there are plenty of free places for developers to play around on GitHub or elsewhere.
A game like Screeps needs to ensure every player has the same number of CPU cycles or else the results are irrelevant.
Thanks again for making this awesome game and please contact me if anything changes.
Cheers,
Dave
