My xbox controller works just fine for the game but I prefer to play with Arcade stick. Is there any plans to support those in the future?

I got my world record 692,538,310 just now on Dynamic level. Yet I have never reached more than 4000+ multiplier so there is potential to aiming at a higher score. Since Dynamic is harder to build the multiplier at low count and Expert's multiplier is limited to 4999(if I have remembered right), it could be possible for me to get a even higher score at Expert. Just want to say this game is so fun for someone aims at getting a high score - that is, you have already got familiar with some other bullet hell ...
