For people interested in 2D development, Yoyogames will slightly change its prices policies next month. The over-priced Yoyo Compiler (some add-on to make the game engine much efficienter) will be discontinued as stand-alone product and will be integrated in the "common" products while the overall price of all products combined will stay the same.

In practice, the prices for HTML5 and Mobile exports will each increase by 100$, Linux and Mac exports prices stay the same.

I wish they would go back to the 20$ price idea! There is a good alternative called Enigma, It uses java so it can be natively used on Linux and windows, and cross compile ( I think it can be used on mac to). Best of all it is Open Source!
