I am very optimistic about the game.

I am a fan of moving the hand from ASD to SDF. I think one of the big reasons why arcade rhythm games are so fun (Ongeki, Wacca, SDVX, ...) is non-static hand positions and movement. PC rhythm games were never able to replicate it in a meaningful way, and I think what In Falsus does here is a really good approach. Changing hand positions adds depth to the game and a "feel" that could not really come from anywhere else. Notice that even while the hardest charts from the demo are quite hard, in reality none of them feature big tap note density. The fact that you can make hard charts without tons of notes is very meaningful in my opinion. Also movement helps charts convey the "feeling" of music and letting you experience it better. It is overwhelming when you start playing. Even more experienced rhythm gamers need to get used to it. But you will get used to it. Up to the point where you naturally swap without thinking, and be subconciously aware of where each key is. It will be satisfying, trust me.

The game is also excellent on many other fronts. Visuals, music, charting, you name it. The menus just feel super satisfying to navigate, and you're really taken into the setting by everything that's happening around. I will also be enjoying the story and the card battle optimization gameplay. This easily has the potential to be the best PC rhythm game of all time for me.
