I downloaded the demo as soon as i saw it was available, i got to play the introduction and replayed "propper rythm", there was no problem there until i tried cranking the dificulty up a bit, apparently the maps wont load as they are supposed to (can still control the characters but there is no music nor enemies). Tried getting the other version and the problem still remained.
Down is a reference pic so you can see what im talking about.
On any other map other than that the message on the top right is a little different being:
Level Loaded
TEST_RHYTHM
Single
Profile DEMO_PROFILE auto-saved while level TEST_RHYTHM was loading
BeatmapParserEngine: osu file format v14
No spawnpoints found!
