I am currently working on a new Android game,. seems to be based on an old GameMaker game I did called Black Bullet Hell. That one was released unfinished and still exists on various game sites around the net,. try this one: Black Bullet Hell (old windows game)
I have the basic game running at a solid 60fps on the Nexus 7 currently,. still need to add sounds and music but I did notice that the MOD music from the old game is still interesting to me, so perhaps I will simply build off that. Not sure we have a free method to add .xm module files to Android projects in ZGameEditor yet,. will check on SunVox to see if that is ready yet, as the mod imports straight into it and SunVox offers so many interesting real time sound mangling effects.
I am planing to do a multi-stage shooter with this BBHell implementation being just one stage, the next will be rather reminiscent of Robotron, and a third area is forming in my mind now as well. I have a very playable two finger shooter system; two fingers to aim (tap or pivot) one finger to move, relative to the touchdown position, so you can see where your are! This system is quite playable with the game designed for it, perhaps a tad slower paced than a traditional twin-stick game, however very fun on the touch screen device.
I also realized I can use the trick where I do not clear the screen when redrawing, and generate some interesting fading tracer effects,. it takes a lot of subtle brightness balancing to get a nice level of the effect, and this is working very will currently.
