Game Engine for Netbooks

I found a very neat game engine called D2D the main features of it is:

• Takes 0% percent of CPU usage (saves battery lifetime when playing unplugged)
• Uses DirectDraw which is enought for fast simple 2D games.
• Supports PNG 
• Fully written in C

Here is some simple game made with it:

It should perfectly fit small resolutions and I no doubt I may run on old Windows 95 machines. I will play around with later on...
