Let's play a little quiz game! The member who can answer the question first may ask the next one, and so on. Hope this will be fun!

So here's my question:

A (classical) firefly touches a (classical) amoeba. The amoeba is neither trapped nor too big (so it does not convert). Yet the firefly does NOT explode! How is this possible?
Hint: "Classical" means that there are no special attributes or something which can only be set with some hypermodern engine.

The firefly remains in its delay state. This happens when it moved to the upper or lower border in BD1, BD2 or PLCK.

Hm, ok, that's another possibility. The solution I think of, however, is independant of the engine you us, it would, for example, also work in CLCK.

Are you thinking of the timing idiosyncrasy that I exploited in RTADash 7, cave K?

No, but this is the solution I wanted to exclude by saying that the amoeba is not trapped!

At what point do you think, the amoeba is trapped?

If you asked me, that is a trapped amoeba the instant, the fireflies touch it. Furthermore, the amoeba DOES convert, which IS excluded by the question.

Here you have an engine independent situation:

Not trapped, not too big, not converting, firefly touches amoeba, firefly does not explode.

Yes, THAT is exactly what I thought of!

This post was merely related to the soultion RTA Dash suggested!


OK, Logic, it's your turn!

What feature of the unmodified BD2 engine was not used by the original game, besides unused elements like explodable Steelwall?

I guess it's about a special BD2 feature (not present in BD1, for instance)?

The cavescan-restart, when a boulder drops into a magic wall, was removed in BD2. But there are no caves in BD2 that combine amoeba and magic walls, so the feature that activating a magic wall cannot stop an amoeba, is not used.

(Arno just beat me to it )
The magic-wall not stopping the amoeba growth?

You're talking about a non existing feature. That does not count.
Calling combining amoeba and magic wall a feature is pretty far fetched either.

No, I'm talking about a real feature which clearly is coded into the engine and most likely not an oversight, bug, exploit or side effect.

Do we need the source code of the BD2 engine to figure it out?

I don't have a copy.

You don't. That feature can also be used in the unmodified PLCK.

I was thinking of something involving the add drawing instruction, but the PLCK doesn't have any of that, so that's probably not right.

Does this feature primarily concern graphics, gameplay, internal workings, or something else?
