I’m glad you enjoyed it!
Good feedback; I think that what’s needed is that when the blocks start to fall faster that there’s a pause and a visual & auditory queue that the speed is changing. I’ll add that in once the gamejam wraps up.
I think it was also because I had already come up with a mental note of how to prioritize the stacking of the blocks into rows and that I was steadily going with this plan when I learned that the game had ended. There was still the weight factor that I only really noticed when I was taking a screenshot.
