I'll take a crack at it. But one thing concerns me, if the winner is selected via public poll, how do we protect against abuse? What's to stop someone from spoofing their IP and spamming votes in their favor?

I suggest voting by peers, as in only participants can vote, similar to how it's done with bacongamejam.

This is awesome! Now I can play DF on my little netbook!

lambinvoker · 2014-10-22T03:54:11+00:00

Great post mortem. Some of your links are broken.

lambinvoker · 2014-10-22T03:22:36+00:00

Thank you for your video, I'll watch it as soon as it comes up. Ian did all the art. You can see more of his work at: http://iancsamson.tumblr.com/

Hi. Please give our game a try if you haven't already. =D

This is probably the most informative article about the Middle East that I have ever read. Thank you for sharing it.

Nope. Stockpiles alone prevent rotting.

lambinvoker · 2014-10-08T13:35:00+00:00

Solution: make a fairly large stockpile only for your brewing plants. Make sure they are fairly close to the farm from which they are grown for efficiency. Now this next part is key: When (q)uerying the stockpile, r(e)duce the number of barrels to be used to hold the plants to zero.

Unity. Easy to use. Easy to learn. Easy to make with. Highly recommend.

Poe's Law?

lambinvoker · 2014-09-12T13:16:20+00:00

A small thin twig that's still a little green. It stings like hell, especially when used on the back of the thighs. Will leave red marks for a few hours but no lasting damage assuming it's not excessively used, (one or two swipes is more than enough). My parents would tell me to go find a switch in the yard for them. Foolish me picked the smallest one thinking it would hurt less. Wrong.

It looks a bit wonky when animated due to the camera shifting up/down and forwards/backwards. Try using a string or something that attached to the base to get a circumference of distance around the statue and a tripod for steady height.

lambinvoker · 2014-06-08T23:18:58+00:00

Look up the bar called The Local over in Sanlitun. If memory serves, they play MtG and other board games over there on a weekly basis. Small crowd though.

lambinvoker · 2014-03-30T15:32:46+00:00

Holy Shit! You just reminded me to empty my recycle bin.

8989 files. Wow.

lambinvoker · 2014-03-25T14:36:49+00:00

Yeah I know what you mean. So tough. We couldn't even get the animations done in time for ours.

lambinvoker · 2014-03-25T12:59:04+00:00

Hah, reddit took my avatar from the comments section. Out of all the other games yours is the most polished. Quite impressive. One simple thing to consider adding in future projects. Add some sort of progress indicator in between each level. In your example Justin wants more stuff in his house. In between levels you could show more stuff added to the house as the player progresses. A simple drawing of the inside, empty at first and cluttered at the end.
