Thank you very much for your feedback!
I too think that intentional placement is problematic. To make up for this pain point, I tried to direct players into placing blocks where they can rather than where they want. For instance, switching gravity makes the falling block fall a little faster, which should make precise placement even less optimal.
It would be fun to experiment with a bigger grid, but I guess that's what we get for the time being :)
Thank you for playing!
