A very well set up game. You get in a rhythm and then the game says nope, not happening. Music is catchy, and basically an overall great game, hold off on the division lol

Too flashy; the background can be removed, but the movement is so wild and very distracting. Having music options is good. The puzzles themselves have a frantic difficulty which scale nicely. I wish there was a number layout where the 0 is below 1-9 like in a keyboard numpad.

Brilliant game with excellent music and is lots of fun to play, plus it improves your maths skills at the same time, if possible I would love to see a mode where you only type the answer and it automatically pops the bubbles in order of appearance.
