I had fun with it, but there are definitely better auto-shooters out there, some even for free, like Holocure. One concept that Kagura implemented, which I haven't seen in other auto-shooters I've played so far, is a map. I really wish more games in this genre had one. The tier leveling up as you play is cool too. However, the game is a bit rough. It's completely playable, but there are some annoying things, like grids on the floor that made it look like I'm playing in Debug mode, enemies sometimes go through walls, and in certain places where there was supposed to be a wall, there are just black squares, as if they forgot to put a wall sprite. There's some quick fun to be had here if you are a fan of the genre but it's nothing incredible, can't expect much from a porn game developer suddenly doing a normal game, to be fair.

Derivative survival auto shooter that has a few good ideas but sorely needs polish and something to distinguish itself more.
+ decent mechanical foundation with a universal player state rewarding not getting hit, a responsive dash ability, and variable weapon modifiers
+ relatively clear visuals
- unprofessional sound effects (enemy cries) and red hit flashes
- poorly thought-out upgrade system which incentives only interacting with the best items
- convoluted in-game progression
- very drab environmental design in the small pool of maps
- several major UI glitches
