Well, I see a few of the minor problems you are talking about. I fixed them, except for the pushed the crates off of the platforms. I can't change that, it's part of the game design and it's going to stay that way. Thanks for the feedback! I didn't notice it starting on level 1! I fixed it though. Good thing you caught that. Well, you gave up agian? I suppose it's alright, since it is just the last level and beyond that is just more text. I'm sorry you couldn't do the final puzzle, or if I just simply made broken and kind of ridiculous. Others I had test it seemed to do it just fine, but thats ok. I believe it should be listed now, since the main problem was fixed.
Thanks for the feedback Durnurd! The final project is right in this post.
EDIT: Whoa, wait a minute Durnurd. When you played level 22, did the (blue)button that fell from the sky fall on top of the first crate? That's why only the second can press it, I thought the first crate would always be exactly where the button drops, but I have another Idea so it always happens. I'll just create the button near the first crate and offset it's path way up so it only appears near it, and so it can drop on it. Sorry it was confusing, and I'm guessing this is why you had trouble understanding.
It's fixed now.
