This is a great game! I have a suggestion, maybe move the health meter a few pixels to the right. When using AV-out on an old analog TV, the sides of the screen are cut off and you lose this bit of information. See the attachement 1DSC00042.JPG .
The bar is in this position because, in the future, it will have two players, meaning 4 bars on the left... so space is precious.
I'd also like to request a port for the GCW Zero. I tried he current version, there are a few errors with the text placement in the opening. After selecting a character the game gets stuck with your character looping the "warping in" animation in the upper left, and the controls become unresponsive, have to kill the process to get back to gmenu. Sorry I'm not a programmer so I can't offer any tips other than pointing you to the toolchain ( http://www.gcw-zero.com/develop ) and letting you know you'd have to make the game write its config and save files to $HOME/.appname if you want to package it as an .opk, as the format is read-only.
I won't, personally, make any other ports to systems I do not own. It is VERY HARD to mess with something you can't see. I already have ports for Wii and OpenPandora and I haven't the faintest idea how those run, if buttons and speed are right, etc. After/when I find a new job, I could look to buy some hardware, but right now, as I said previously: no paid job, no dice :-P
That said, porting the code is piece of cake and I can help pointing how to build and add changes to support the new system, if anybody wants to do the job (originally, Pandora por, for example, way done by sigma-nl).
