A very very good simple puzzle game! An awesome monochrome aesthetic! Those puzzles were difficult but so satisfying to solve! The placement of the pressure plates made me realize which keys were eligible to be sacrificed, so I had to build a mental path using only the directions I'd have left! Let met tell you when I first solved the puzzle with one pressure plate weight downed by the Up key (one of your screenshots) I was doing a little tiny celebration (soft little pounds on my desk and a "f yeah I got it")
This was so good. Great job!
