Full disclosure; Team Spaghetti does not endorse recreational math. We're more of a "Guestimate with our feelings" kinda group. We made a game about a bullet who wants to make his mom proud and screams in terror midflight, if that helps you picture my mental state.
That said, this is not a bad math game, by any stretch. It's no "Math Blaster" but it's dynamically engaging once you get your head wrapped around it. Speaking as the team's programmer, this is the sort of game I'd probably have more fun picking apart the codebase of than actually playing but again; I don't do math for fun. I do math to facillitate the fun things. That's just me.
Insofar as critiques and things to work on, some have brought up the UI and yeah, that's not amazing, but it's well within 48-hour jam territory for me. That's fine. The big thing from my experience was being dropped straight into a ten second countdown and immediately being under time pressure to parse all the things happening on the screen--many of which being wholly unimportant. That's how you give anxiety attacks to the math-averse.
On the whole, is this my kinda game? Personally no! But I can't deny that there's a certain level of mathamagical wizardry that makes it work, and work fairly well for what it is.
