Can You Beat Half-Life Without Jumping?

Questions half life "enthusiasts" will probably have:
"Why didn't you get [item] earlier, or why didn't you take [alternate path] that would have been so much easier?"
This was my second half life playthrough ever, and whatever route you're thinking of is probably very correct, but I had no idea about it at the time.

"Why did you use HD textures? They look so much worse."
Same reason as #1, I had no clue HD textures were even a thing when I did the playthrough.

"It looked like you jumped at [timestamp]."
I promise you, I didn't. The only times I jumped in this video were in demonstrations and I hope by overlaying them over actual footage it made it clear.
