Pretty cool game! I see you've worked on patches to address the most pressing concerns, so congrats there! If I could give a little more feedback, I think the hitbox/click size of the number buttons should actually be larger than the visual. As mentioned in another comment, it's a tad frustrating when you click the number and you think you clicked it, but in reality it doesn't register. I think giving some leeway with those inputs would help exponentially! This is a similar idea in other genres, like platformers! In platformers, any spikes should probably have a smaller hitbox than the actual visual to make the game feel more fair. And same with coyote time too, giving the player a bit of forgiveness for messing up their inputs by just a few frames. I bet you could apply the same design principles here to improve your game!
Overall, really neat concept and definitely room for expanding on it! Congrats again!
