Monkey is a brand spanking new programming language that allows you to create apps on multiple platforms with the greatest of ease.
Monkey games can then be run on potentially hundreds of different devices – including mobile phones, tablets, desktop computers and even videogame consoles.
I coded my dwarf zombies something 1-week game using Bmax and I’m testing the Monkey demo and porting my code to monkey code (just for the sake of testing how it goes)… which then helps me port the game to HTML5… and at least in theory to XNA and to iPod (now I can justify the need to buy Xbox 360 and a Mac, *cough*)
Anyways. If you want 2D development (I suppose at some point in the distant future somebody might do 3D too, but for now… it’s 2D). If you want it to be super cross-platform… then check it out. I’m checking it out this week or so.
