It's so cool that you like rhythm games! It as my fist attempt at one! Do you have feed back on how we can make the rhythm or tactics aspect better!? We have a few future plans for the game so we'll be adding more songs, cards and syncing better the music with the attacks!
The game felt hard at times, but I cant really tell if it was the tracks or the control scheme, maybe experimenting with a horizontal layout will yield better results? The tactics aspect felt really cool, in order to better it I would add more options. Overall good job!
