La Torre De Nozar
About
"La Torre de Nozar" is a short and simple freeware educational beat'em up that I've made in two weeks while I was learning how to program in python with pygame, a long time ago (2012 to be more precise).
It was committed to an annual contest of educational games at Uruguay and won the first place.
The game is extremely basic... so, consider it like a short of simple but funny "mathematical beat 'em up", however, I'm surely that you will enjoy it if you give it a try.
