just, So you know...

The unused Enemy sprite, the "cat" is actually not unused. It is actually used. I can prove this, because the cat is hidden in a block somewhere in the outer wall, and has a script.

Just so you know guys, ITS not an enemy, and its used...

 

I think you mean the "debug cat" in the credits.

 

Yes, that. XD

 

What did the script say?

<KEY<MSGThanks for helping with the
debugging.<NOD
This is as far as the game goes
for now.<NOD
I'm thinking I'll make this next
stage the last one.<NOD
Wonder how far I can get in
just two months...<NOD<END

Also, I found this bit of code in blcny2, the one right after the fight with the undead core. No debug cat, or anything, attached to this one though.

<PRI<CMU0033<MSGThank you for testing!
The next part is still
under construction...<NOD<RMU<END

Probably refers to Hell/Sacred Grounds.
Just little bits of leftover messages, nothing special really.

 

Those are messages to Pixel's beta testers. He overlooked them in his final release. Or maybe he left them in on purpose. Who knows? I think it's neat that Pixel was originally going to make Plantation the final area.
And yes, that "next part" is Sacred Grounds, which Pixel threw in as an afterthought.

 

It was an EVIL afterthought.

 

Also, I found this bit of code in blcny2, the one right after the fight with the undead core. No debug cat, or anything, attached to this one though.

It's apparently bound to a NPC somewhere in the wall to the right or something.

 

Because every game needs to have super duper secrets that no one is supposed to know about.

like that half naked guy in Halo 3.
