When you have Climbing Gloves, ledges act very weird.  I am trying to jump over something two tiles high, and normally if you run and jump against it, you would grab the edge, but with the Climbing Gloves, you just coast right over.  It's very dangerous and doesn't make sense.

You don't even need climbing gloves. If I jump to hang on a ledge, but press the button really fast, the guy will jump a short ways up but never enough to get up. Then you need to regrab the ledge and hop up. It can get time consuming and a bit annoying.

Tiny bug.
That's immovable too, but if you want another photo of it with a normal block there, I can do that too.

Hello. I figured I'd join the TIG Forums some day, and now I have a reason. I just wanted to add my two cents.
First off, I really love Spelunky. It is a very addictive game. But, I just want to bring to your attention some bugs, and make some suggestions. I hope none of these have been said already, I don't want to be redundant.
Bugs-
-I was standing in a spider web with a wall directly in front of me. I accidentally threw the rope while ducking and it went through the wall and deployed on the other side of the wall. I guess it's better than it deploying in the wall, if that's intentional.
-I just finished making a stage in the level editor, and then I exited out to the main menu and started a normal game. After I beat level 1, the level editor screen opened and it displayed the level I had just been editing.
-This is incredibly hard to do, so I don't know if it's in v99.5, but there are two things I could do in earlier versions with the shopkeeper.
1-When I pull out a bomb in the shop and walk right next to the shopkeeper (It's really tough to get it just right) and ignite the bomb, the shopkeeper will go crazy (like he always does when you ignite a bomb) but instead of shooting me, it plays the hurt sound effect a lot and the shopkeeper slumps over dead.
2-I used to be able to rob a shop when dead. I would intentionally make the shopkeeper kill me, then, when I landed on an object, I'd press down and X to pick up an item- while dead. Certain items were erased after dying even though I picked them up, but I was able to keep items like the jetpack and climbing gloves, I could use them in the title screen and, most notably, start out level 1 with them. I can't do it as of late, but, like I said, it is very tough to do.
-The Teleporter likes to murder me... a lot. It can teleport you anywhere from 4 to 10 spaces, right? Somewhere around. when I use it, if I use it into a block, he'll usually go through it and land safely on the other side. If that's not possible, he'll go up a distance. however, if there is no empty space to go to, he'll die. That is okay, because otherwise what WOULD he do? However, a lot of the time, the way IS open for him to go, but he just dies anyway.
-Whenever I end Spelunky in ANY way, even the Quit option (F10) you have enabled, the game ends, but then I see the "send error message?" prompt. (I'm using Windows XP).
Suggestions~
~Everyone knows it's easy to rob a shop. Take your item, jump over the bullets, go somewhere safe and wait for him to leave. Then you can rob the rest. I like this, but I don't like the frenzied shopkeeper at the end of almost every level after. Now, I see that's the only way to punish thieves, and I guess it's okay, but don't you think when you kill the shopkeeper that wouldn't happen? After all, how would word spread around if he's dead? And, from a gameplay aspect it would make some sense. If you put your life on the line to kill a totally overpowered enemy, why would you be punished with more of them?
Running away from the shopkeeper deserves what you have now, but not killing him.
~When you fall a great distance with the girl, you'll get hurt and she'll revert to standing there. That's good, because then she'll stay there while you attempt to get up. But what if you want her to stay there any other time? no matter what you do (with the exception of falling from a great height) she will always get knocked out and start to run away. You should make the down and X drop turn her to normal instead of confused. This would also help in kissing booths when you pick her up, decide against buying her, and drop her, then realize she's confused and will start running away. Right when she inevitably passes the door threshold, you're wanted.
~It's such a let down when you walk into a  shop and realize it's all bombs. I think it would be pretty cool if only one item of a type could be in a shop. Arguments could be made to keep the multiple items too.
~In the level editor, you should set up a "Shop editor" Where you can place items in a region and they will become buyable, with a shopkeeper there to keep order.

Sorry for the really long post, hope I'm not repeating anything.
Great game!
