One of my fav games when I was really young was actually a maths game on my Atari ST, so it's cool seeing a fun looking and stylish game like this, nice one!
Aw man that sucks, I got asked to do some environment art for the project but had to turn it down due to other work at the time, would've been cool to work together. Looks like a lot of fun though, gonna check it out :)
