Yes, Cascade 100 % is more notable than, e.g., The Great Lemming Caper. Cascade 100 % is such a drastic difference of intended solution (already not trivial) and what the community can find.
This will indeed tie in nicely with the community research on DOS L1 min-skill solutions, physics bugs, ... It's been a while that we investigated DOS L1 full-time, but in the early 2000s, we dug into L1 thoroguhly with excellent and surprising results.
Right, DOS is one of the first ports, and the development was on Amiga. DOS cuts many water objects. And DOS gives 12 builders on Triple Trouble, where Amiga gave only 10. With 10, Triple Trouble is far harder to execute.
