This is what jam games should be. Just fast 1-5 max minutes. Sometimes I find myself playing 30 min of a jam game. Cool game. Some more complex equations would be cooler, cus now it's targeted towards 1st graders. If you've brought the level up a bit, like still get answers with one digit, but square root of 9, get in some minuses and multiplication. If that was in the game it would've been 10x better.
