Some things that I like and I think that needs work
The things I liked!
+ Gameplay is great, a spiritual successor to Parappa the Rapper with key difference which is supporting the bar. I usually see this in modded Parappa videos but man it feels great to play and listen when you go along with the "rival"
+ Music is great as well! My thoughts for this is like if I have a music player and I'm just in it for a long car ride, I can use this to pass the time and enjoy the beats
The things I feel that needs work...
! There are few to some cases that inputing an incorrect key would literally sabotage the entire line and there is no way of salvaging it, I would get if my rhythm is wack but accidentally hitting a wrong key and unable to redeem just kinda sucks
! Supporting the Bar needs work, especially if you decide to have levels that require input immediately after finishing a line
! Scoring System needs work, gives me false hope on certain cases like if I get a 1346 on Funk and then the results tell me I got 1052
! Having Vocaloid Voices (if that's what I'm hearing) is good but I wish they are louder than the music since some of it feels muffled to the audio track
Overall, great game demo, I really enjoyed the concept and after playing it for like 3 days, grinding for S Rank and attempting to get Acsencion Mode, I really enjoyed the experience, despite the small problems I ran into. Here's to good luck on your game!
