Core Mechanic: I love a good puzzle game, and this is one of the coolest I've seen. I'm just annoyed I don't have the time to sit with it for hours.
Game Feel: Actions all have smooth animations and nice sound effects, navigating menus is buttery smooth and buttons don't have awkward delays on them. Also seeing the numbers pop up was pretty fun.
Visuals: The whole game looks super pretty and chill, with a cohesive art style. The color of the fonts are clear and distinct from the background, and the yellow for my inputs is a nice contrast.
Sound: The music and sounds are serviceable; I don't have much to say about them.
Theme: Seeing the numbers get really big and the resulting confusion and mystery is overwhelming, and all from just 4 digits
