The idea here is to shine a light on these hidden interests and the little (or big!) mental blocks that come with them. If you're already rocking in those specific areas – or you've been there and figured out how to get past similar hurdles – please chime in! Share some helpful resources, dish out general advice, or just give a nudge of encouragement on how to take that intimidating first step.
Let's help each other get unstuck!
Anyway, I’d heartily recommend Microcorruption[1]. It’s really good fun, uses a fairly simply assembly flavour (msp430), and introduces new concepts at a nice cadence.
Shameless plug: I’ve written up a bunch of the solutions in “tutorial form” on my blog[2], but I am incredibly slow at getting new posts out (although I do have the next ~4 levels in nearly-complete drafts).
