Tried the browser version. I like the idea a lot - falling blocks that turn into equations for attack and defense is a fresh twist, and the gloopers are charming. Two honest notes from my session: the tutorial is long, with a lot of text to read before you get to actually play, and I'd rather learn one rule at a time by doing it. And right after the "Let's try that again!" step, the game hung for me and I couldn't continue (browser, Chrome). Might be worth a look. Looking forward to the deckbuilding part - the core loop is promising.
