I was looking for someone to play with the math powers in this jam! :) Nice take on the theme! Although it would be even more nice if it wasn't only about the enemies, but about you as well - and there could be some cool mechanics related to these math powers.
That said - I really liked the tasks mechanics, they are quite refreshing compared to just pure exp-gain. Although the "don't shoot for X seconds" is a bit too hard %)
