Very short, but the concept is used very nicely!! I noticed that glitch as well, but I didn't know when it stops or notice that armin is invincible. there are also other ways to get that trick to happen - but I didn't write them down so >_>

I enjoyed this cave very much.

What a very nICE level. It is very COOL to play. It really CHILLED me to the bone.

ISA!! USING FAKE CRATES!! NOT COOL!!! I was wondering, "well geez, I absolutely cannot figure out what I'm supposed to do here. Maybe armin can make that jump since he can jump shorter" and then sure enough he goes right through the damn metal crate. I killed myself earlier because I thought I was stuck!! For someone who preaches being user friendly, you should be ashamed of yourself

So I had to play my own level again to understand what fake crates you mentioned, especially when you mentioned the shorter jump...and my question is, do you actually play with Armin in this level? Did you miss the unique mechanic?
edit: I think I misread your post, but still, you should have tried at least firing the arrow before committing suicide. There was no trick involved, no speed trap, just fire the arrow.

For why I used fake crates to drop the guy - try to make him drop any other way. He dies to explosions two tiles beneath him, he dies to crates falling one tile below him, he is hit by arrows flying two tiles below him. I went through a lot of frustration before I even noticed that it was possible to drop monsters AT ALL, and again, only then by using fake crates. It's 100% impossible to make monsters fall if you do not use fake crates, but believe me, if it was possible to do any other way to drop the mob, I'd do that.

Reading your post, I realized now that the problem I had here was that I didn't realize that the enemy dude had even dropped, which makes me feel really stupid because it seems so obvious now. Knowing that he drops from the fake crates, I understand why you would use them. Had I noticed that, I would have probable figured it out.

And yes, I did use armin. I'm guessing the concept here is that we're somehow supposed to play as hannah and have armin float all the way down? But it looks like I can actually get armin down the natural way, which is actually kind of cool if you can.

The mechanic trick is that, if you make Hannah and Armin spawn a certain way, Armin will float in the air at the same height as Hannah, invincible, until he touches the ground or hits a crate above him. It plays like HatPC in a way, but with somewhat different physics and a restriction on how Hannah may move. Mostly, it's very cool.

I didn't get to get very far into it; this was the last cave I filmed for the shoestring video (despite that L34 was the last cave shown in the video), and I my time playing it was cut short because I had to leave. Playing it more, though, what am I supposed to do with this area:

x+ wxx=====|=  mw  wxxx
x== ww     b  mx  mmxxx
x    " mx=k  koxmmxxxxx
x v < <|<    ==xxxxwwxx
x   m" wx      xxxw""xx
x=v=x   xx=    wxx   wx
x > w^m>ww mb  vww  < x
xx== m|m mm|kmm|m> |<mx

The ladders I highlighted. If I hit the arrow before going up, when I try to fall onto the ladder I fall too low and automatically hit the up-pointing arrow, killing me. If I don't hit the arrow, I think I risk death because for some reason you can't fall off ledges with spikes at the ends (which you can in hatpc) without risking death, and even if I don't die there, that seems very difficult. Is there something I'm missing here?

nvm: just figured it out

You need to hit the arrow two tiles to the down and right of the bottom ladder and bounce up on to the ladder.

Yeah, I figured that out shortly after posting.

Usually I think that your caves are too hard for my taste and I can never hope to really do much in them, but this one was different; I actually managed to beat it all at once, without using the floating armin glitch. Then I went back and did the part where I did things differently, and did things the way you intended them to be done, and completed all of that stuff (but didn't go on to complete the cave). So I can effectively say that I seen everything there is to see here. And I like it

I think I honestly preferred doing it without the glitch more than with it. Something about playing as armin is fun. Also, playing as armin allows me to clear out that enemy before sending hannah through. Since this was a really short level, it doesn't deserve a very high difficulty rating. And I actually like that, I wish more people out there would make smaller levels that I can actually beat.

I didn't even know nor intend for this level to be possible to be beaten the regular way, so props to you for that.
