I’m in – Community Challenge
So yeah, I’m in. Tools:
OpenFL (openfl.org), maybe some framework for openfl, GIMP, LMMS, Tiled map editor (in case I make the game tile-based), FlashDevelop as an IDE. Also I upgraded for Win10, Let’s see how development goes with it 
This time I came up with another challenge for myself (and maybe others). And it’s on a whole new level.
The Challenge: I’ll try to contribute to the LD community as much as I can: help people in IRC, post progress updates, share ideas… You should try that too! 😀
