Im not good at math puzzles :p but the game works well.
you should add some hints in each level to make it more enyoable. (I solved some puzzles, but most I brute forced)
well done for a first game. Consider using Unity for your next games, it is also free (if you dont use it for financial purposes, so for GameJam its perfect) and there is a lot of tutorials out there to help you.
Great job :D
