I love rhythm games, and this is a great base for one! I like the concept of a VSRG that's not just guitar hero, and I think this could be improved to be an amazing rhythm game! I think you could definitely benefit from more polish, like the missiles doing something whenever you hit a missile successfully. Additionally, I think it would be good to have an additional distinction between the missile types, as if you have 2 missiles close to the opposite edges of the screen the gameplay feels a bit unfair. For example, maybe left and right missiles could come in moving to the left or right a little bit so you can distinguish them more easily, and some could come in faster as well. However, I think this current system you have has resulted in good gameplay, and it is a good rhythm game base, especially for the short time it was made in. I am not sure if you manually charted all the songs, but if you did, I would recommend taking out some of the break sections, as there were some 20 second+ periods in songs where I only had to hit one note every few seconds for that entire period, and some periods where the music didn't feel super well synced to the missiles. Great job though, most of the charting is pretty good!
