Physica - a casual platformer
Physica is a casual platformer game in which you drive a block in different levels from its starting point to its goal, avoiding hazards (yes, it is as simple as it seems...)
The game came out while I was trying to make a 2D physics engine (based mostly on this article's ideas: http://buildnewgames.com/gamephysics/): after a while I tried to make something more than falling blocks and this is what came out.
The game is still under development: while the physics engine itself is pretty complete and game engine and user interface are finished, there are ten levels only packed with current version; I am planning to add many more of them, of course :)
The game also has a pretty advanced level editor, which allows you to make your own levels (if you do so, please share!).
