I'll be happy enough if NL compiles as 32-bit, which runs fine on x64_64.

The GR32 port wouldn't be urgent for me. Everything here runs on x86_64.

x86_64 is included in this case if NeoLemmix is compiled as a 64-bit app. Maybe GR32v3 addresses this; but one of the biggest reasons NL remained a 32-bit app is due to GR32 not having the same optimizations in 64-bit.

I assume: When you click a radio button on the left, you don't affect the final result (summarized at bottom-right), but you make the program show a different set of controls at the top-right. Choices in the top-right affect the final result even after you click different radio buttons on the left, which hides the earlier top-right choices.

In this case, the Replay Kind radio buttons are action buttons with immediate effect, not choices, which violates Nielsen's guideline #12 on Checkboxes vs. radio buttons: "Use checkboxes and radio buttons only to change settings, not as action buttons that make something happen."

The column of radio buttons isn't the appropriate UI widget for Replay Kind. Instead, the dialog should have tabs, one tab per Replay Kind. The different Replay Kinds should be a row of tab handles, probably across the left because you'd need multiple rows if you put them across the top. Nielsen: Tabs Used Right, guidelines #10 and #11, are at odds with each other for us here.

I think you should keep the summary below the tabs, it's succinct and good. Although -- if we need the summary at all, keep in mind guideline #3 of Tabs Used Right and weigh the tabbing against a huge dialog that shows all Actions for all Replay Kinds at once. Most likely, tabs and summary are fine.

Having radio buttons for Replay Kind would be fine if, after confirm and exit the dialog, the Action for the single chosen Replay Kind were the only Action to happen, and nothing happened for other Replay Kinds. Then, the radio buttons for Replay Kind would be choices that affect the final result of the dialog (you'd un-violate guideline #12), and the immediate showing/hiding of Actions would be nice progressive disclosure of the appropriate sub-options for the single chosen Replay Kind.

Thanks! I like your collection as well. Awesome! You have TWO Lemmings plushies! Very nice, indeed.

Keep up the building of your collection and I shall say, I have never seen those Lemmings games before, nice too! Thank you for sharing, Paiy!

Stream is over! I streamed geoo's Classy rank. Recording will remain for 14 days at: twitch.tv/simonnaar

The Climber Predicament & The Floater Predicament: I have a meaty backroute including a finnicky trick near the exit to lose height. I have several spare climbers and floaters, therefore this replay (after you re-point it) will solve both levels.

Lab Map feels intended. Nice! Flopsy found the loose idea independently from me.

Steady Supply: The main idea of my solution feels exactly indended. Nice! I'm sure I can improve the details to make the timing easier for myself. I had 1 builder spare and could spend it to turn a mistimed lix.

Clam's Missing Cubes looks intended. That's a tricky skill-minimizing variant of our research on Clam's Pachinko, and to solve it now, you needs the right idea from the start. Flopsy believes he wouldn't have found it himself.

This Level Socks: Feels reasonably close or intended.
