I released my first ever Android game 10 days ago and already got 17.000 downloads, so I'm quite happy already!
A big issue I'm having though is that I get a lot of 1 star ratings because the game is running too slow on old Android devices, while many others are voting 5 stars (probably because it runs okay and of course because they like it)
1) Could I fix this by lowering the frame rate to 25? I noticed the frame rate is set to 50 by default. If I change it to 25 it still seems to run okay (though some thing in slow-mo) so this would be an option, but would this speed up the game on older devices?
2) Any other suggestions to speed up for older devices? I don't think I'm using any "expensive" code, since it's quite a simple game, so I don't expect a lot from optimisation there. But still, tips in that field are welcome too!
3) Is there an emulator or anything I could use to at least get an idea on how the game will run on old devices?
