I enjoyed the game, I did get a bit confused to begin with regarding consecutive pairs of numbers, I kept aiming for 1, 2, 3 rather than 2,2,2 etc.
I like the art style, it has an elegant minimalism to it. Though I do think the 3D angle in the capsule image is much more visually appealing than it is in game (assuming they are the same assets).
Like others I had treated it as a puzzle game more than a rougelike-score chaser, so I see a bit of a mismatch there.
I have a recording of my playthrough that I will send your way so you can see my thoughtprocess in real time.
Overall a good game :D Well done!
