The 2016 Annual Roguelike Release Party (ARRP) will be held on the 17 and 18 of September 2016. (Link)
Releasing during the ARRP might bring some extra attention from the wider roguelike community

It's a day late, but I've contacted the RLR hosts. The recording probably won't be before the 27th of August, so there's still time to join in.

That's my favoured method too. I'm a bit too keen not to mess it up, so I end up hoarding about 15 cans of banana flesh before I try it. That often means I'm well into GC before I get the prize. I probably ought to just settle for Zolku's bananas instead.

They do know that there's exactly one person running around town carrying mines and polymorphing themself... and the dolphins probably know how to get fingerprints or DNA off a shard of mine shrapnel. If they're not affected by polymorphing.

How do you get the gas grenade at the middle of the southern wall to explode without affecting you? All three locations you could throw it from are inside the cloud.

Oh! That's great, thank you so much!

Sure thing, chaostrom!
I've sent private messages to fejoa, Zayre, Ighalli, and Z asking for email addresses. I'll contact the RLR hosts once I've got email addresses or withdrawals from everyone, or in a week (on the 10th of August).

Skype lets you make test calls to their servers to check the audio quality - I'd recommend trying at good and bad internet times.
The people who've expressed nonzero interest are:
* fejoa
* Zayre
* Ighalli
* Z
* chaostrom
Mark Johnson and Darren Grey were both positive about the idea on Twitter.
I could join the panel if necessary, but it sounds like we have enough.

Ernomouse: No problem!

I think we've got enough volunteers, and I can't find any contact details for J_Kahvi, so for now the way forward is probably:
1. Gather email addresses and start a group email with Darren and Mark,
2. Use Doodle polls to find a date and time that suits as many of us as possible,
3. Gather Skype names and record the show.

chaostrom: RLR often has people from Australia, the UK, and the US in a single episode, so it's worthwhile to try to accomodate your timezone - especially if fejoa is in a nearby one. Slow internet is more likely to be a problem - is it slow enough to make voice calls unintelligible?

The benefits wouldn't last, though.

Smooth boundaries between terrain types isn't too difficult. One option is to assemble each tile from four quarters, marching-squares style. With two terrain types this needs one terrain type to be "dominant" over the other - floor graphics intruding on wall tiles or vice versa. I'm not sure how this wouod work with multiple terrain types - it might need them to be ordered.
A more complex option is to use corner Wang tiles. See the Civilization 3 terrain tilesets for an isometric example. Each graphic tile is made of the adjoining corners of four geographic tile, and the display is offset by half a tile in each direction. So similar geographic features might be displayed differently, and the visual boundary between sea and ground could cross the tile boundaries.
The problem with these solutions is the number of tiles needed. With N terrain types and no constraints on terrain placement you would need N^4 corner Wang tiles to cover all possibilities. That number can be decreased by constraining which terrain types can be adjacent.
