It should work now.
And here is what you asked for.
Sure. World 6 level 8 froze at least 6 times in a row, all in the same spot. Possibly more before I started counting.

The game had trouble loading in the beginning. That was the second time that happened. The warning screen takes a variable amount of time to pass. I'm not sure if it is related. The level starts at around 1:20

Here is my next attempt.
I remembered that world 3 froze for me too. I played until it froze then went back to take a video of that level; unfortunately I miscounted.
The level starts at 1:30. The warning screen took a long time. I attempted a third time but it didn't freeze.
I just played until it froze; in level 8. The level starts around 4:00. At this point I realized double-tapping space is the most consistent way of passing the warning screen. It didn't freeze the second time I played that level.
If you want any more feel free to ask.
