Since the steam widget does not support Oculus perfectly, we have contacted Steam technical support, but this problem is not completely resolved for the time being. Otherwise, the game will appear handle vibration bug and picture jitter problems.
DrumsHero is limited by cost and manpower, and there are many imperfections.
But we will always try to improve the game experience and make it a classic game like guitar hero (It might be a long time). The players will walk with us, We believe! :)
