I’ve just started dev-blogging about “ROBOT-SB”, a retro game concept I’m working on, and figured I’d start with some of the “pixel-perfect” issues (config.lua settings, to filter-or-not-to-filter, perfect device coordinates, etc) that cropped up.
It’ll likely take me a few entries to cover it all, but here’s part one: http://davebollinger.org/robot-sb-dev-blog-pixel-perfect-part-1/
I’ll try to keep this topic updated as new blog entries occur.
Out of sequence (I’ll get back to the “pixel perfect” topic soon) but pixel art has been occupying me recently, so:

adding rocks and dialing up the player explosion:
(and a time-dilation effect at game-end that I might talk about more in the future)
Dave,
Thanks for taking the time to do this blog; I think it is helpful for devs of many levels. Thanks for sharing your experience and knowledge with others.

“pixel perfect” part 2: http://davebollinger.org/robot-sb-dev-blog-pixel-perfect-part-2/
tho i still don’t quite get around to discussing config.lua itself! :D next time.
rather I’m still laying the groundwork - i cover a couple of more general topics re display quality that might even be of interest to non-pixel -type displays. maybe?
current state of the actual on-device retro fat-pixel display:
You’re welcome, glad you’ve found is useful! :)
Cheers

…where i finally get around to actually presenting something!
http://davebollinger.org/robot-sb-dev-blog-mines-rocks-and-difficulty-progression/
this week saw the introduction of mines, which along with somewhat-related rocks, spurred some thought on difficulty progression
Thanks @davebollinger! It’s always fun to watch pitfalls I wasn’t aware of being solved in advance of then I need them :) Solving problems is so essential to programming but, outside of the forums, it’s a pretty solitary endeavor. I always feel enlightened when I get to see how another mind approaches a solution. Thank you for sharing!

@sporkfin: welcome!

Difficulty curves aren’t tuned out this far, really just an experiment, but kinda fun as a “what if??”:

plus some not-so-exciting-yet-still-important work on options screen, now functional
That is looking seriously cool. Couple of quick questions…
1: How soon until it’s finished? I really want to play this as it’s exactly my kind of game.
2: What software do you use to do the video to animated gif thing?
sooner rather than later, but no definite timeline (want to beta test? android only. if so, pm w/ email)
Ah poop. Would love to test it for you but unfortunately I don’t have any android devices 
I have 10 Android test devices if you need a hand.
I appreciate the offer!, though I suspect you have enough on your plate as a dev for the type of testing actually needed. I pretty much have device-testing covered, at least for android. It’s play-testing (difficulty-progression, cost-balancing, etc) that could use feedback, but is more “work” for the tester.
talkin’ 'bout bitmap fonts: http://davebollinger.org/robot-sb-dev-blog-bitmap-fonts/
fire-colored fonts are still cool, right?
old skool!
I do love a vertical shooter so I would so fit a bit of testing into my complicated work schedule.
