I am not sure if this is the right area to post this, but there was a new game released recently called "Black Castle". Its been programmed for a gameboy and there is also a voting going on, to check if people are intressted in a cartridge version aswell. It is avaible for free HERE in this german forum.
An enjoyable short platformer, I'm not a fan of the axe's trajectory as it can be hard to hit enemies that are too close to you but other than that, a cute game like this should probably be sold for money.
