Free-to-play game I tried out for a bit. Good soundtrack by Zuntata, of Taito fame.
The game is a 2.5D freeroaming shmup, where you move on a two-dimensional plane horizontally, but the plane tilts if you lock on enemies above/below you, allowing some vertical movement. It's a bit on the easy side due to the very generous healthbar, but taking hits drops your score multiplier.
