You are a square, a 20x20px square to be exact. Jump your way through the levels without hitting anything. "One Square at a Time" is an open-source arcade game and is similar to the flash game "Space is Key" by Chris Jeff. It is programmed in Python2.7 using pygame, therefore it should be easy to port to lots of other operating systems, but I can't test that at the moment, since I'm doing the work on my desktop Linux PC.
Added a way to load different maps using terminal arguments + new mappack
Added a new way to load the different maps you've made by using a terminal argument.
If I've got a map called foo.map, I'd start the game like this:
$ python2 CApp.py foo.map
Also started on a Space is Key mappack, which is very dull at the moment, because I find it hard to make it just as advanced as the maps in Space is Key really are.
