I really enjoyed the unique concept and art style of your game! The thumbnail caught my attention, and the dancing knight was a fun surprise (I kind of hope I was playing as the dragon though haha). The animations and art style definitely added to the overall charm.
However, I encountered some challenges while playing. Typically, dance games start right into the dancing segment, so it felt a bit unusual to begin with just one arrow followed by a 20-second pause without any arrows at all for the song's intro (maybe a different song would avoid this problem?). Additionally, jumping straight into Expert+ difficulty with endless chaining for the first song was quite intense and might be overwhelming for players new to this type of game.
If your game features multiple songs, having a music selection option could be good too since the first song didn't fully grab me.
I also experienced technical issues with arrows not spawning consistently. It seems like there may be a problem related to losing focus of the game or changing tabs in the browser when the game is running that affects arrow spawning and gameplay synchronization.
Technical issues aside, nice work and looking forward to seeing how your game evolves!
