Pretty interesting! I think there were a lot of moments were it was hard to see what was going on exactly, the text felt quite small and the numbers on enemies was unreadable in a lot of areas.
What could probably help is leaning towards a darker contrast and/or adding outlines to the text, as well as enlarging them.
But! Interesting concept for sure. I kind of wished this leaned more into being truly 1-bit, with no grays, but it does look interesting as is.
