i found it very frustrating to play where the controls are touchy and it was near-impossible to avoid most asteroids/debris because of it (and maybe decrease the amount of objects coming at us while ur at it, at least at the start). if you increase the size of the v-stick or otherwise gave us more-accurate control, i believe it would help.
meanwhile, red text on a black black background is tough to make out at low resolution (on my smaller screen); a change, there, would help, too. we might be talking about an increase in resolution, in general, to solve both issues that i have with it, as is.
otherwise, i'd say it's a good start. and, you now have 1+ Installs
thanks for sharing!
