This game is a really interesting concept, and I'm absolutely loving it! For this game only being in beta, it has a ton of potential.
I was worried when i tried the first level, and was hoping that the charting wouldn't be bad, and it wasnt! Especially on Hard mode for "Fallen Demon" (Really awesome song by the way!) the charting was really fun to play, and very well timed and mapped to the song. Aside from the glitch where once you get passed 1000 combo it makes the left most arrow register weird, it was fun to hit the jacks throughout the song and streams during build-ups before the drops.
Even though the mapping was easy for me to play, it was super hard trying to not to stare at the background while playing at the same time hehe.
I would definitely love to help out with creating the game if possible, like creating some charts for new songs, or just helping out in general, or something like that :D
Cant wait to see more!
