Level-playing
rhythm.cafe This is a level searching website where you can find some custom levels that are fair for you! This website has moderators, which check for fairness of every level. Levels that do not follow the rules are hidden by default, but can be activated by default. If you wish to post a level into this website, you may post an rdzip in the rd-showcase channel inside of the Rhythm Doctor Lounge. (This website, nor the discord server, is not affiliated with this Game Jolt community)
RDL Setlists These are setlists that can introduce you into custom levels! These setlists show levels created by the members of the Rhythm Doctor Lounge, and currently include many different themed sets, as well as creator setlists and event setlists. If you have some feedback, for example if you think a level is way too hard, you may post them in this thread. (a thread in the rhythm doctor lounge)
