Great little game, and very polished, the animations and transitions are perfect.
The memory puzzles start off easy but get really brutal near the end, which is great. I'm not sure how the stats affect the gameplay directly, if at all. I went spotless until I started getting the two line letters + directions and subsequently messed all of them up haha. I still managed to get an A with 90% on all bars. Maybe the grades bar should deplete with each loss and missing sleep should make the timeout go faster.
Sound design is on point and authentic sounding. Palette chooser is a nice touch.
I quite enjoyed it! Great stuff!
