Dodge 'Em
Another game knocked up using my game engine Itchy.
This is based on Escapa!, a game that takes about 10 seconds to play, but is strangely addictive.
Dodge everything, and don't touch the walls. Sounds easy and looks naff, but it's quite compelling.
Try the many different levels, each with their own personality. There's different kinds of obstacles; some bounce off of the edges and some bounce off of each other.
When you have started to master the basics, head to the later levels. Every few seconds your character changes colour and you need to avoid obstacles of different colours.
