>Game made with Dizzyga V2.5b engine.
Where I can read about this game engine?
Viewing post in Dizzy's New Adventure Demo comments
You can learn about engine here: Dizzyage home
But, must warn you, this engine is Windows only. And of all adapted to create Dizzy-like quest platformers.
Also last public version was v2.4 (in 2010)
Version 2.5 is a few improvements and fixes that I've made myself and it's not yet available for public use.
