Thanks for playing and let me know what can be improved!
When I said “a lot”, I mostly meant it as an acknowledgement of your own list of planned features. That said, I think graphics are quite basic. I also felt the gameplay was “frustrating” in both good and no-so-good ways. I felt more rushed than I personally like to be. The controls felt too sensitive sometimes, and the target areas too small and unforgiving tolerance-wise. But to me, a fresh and intriguing concept is what matters the most, and in that sense, you did an excellent job.
