This game is incredible - very intense, and indeed it is reverse bullet-hell. You want to soak up all the orbs, yet you still have to manage the hordes of round drones (I hate those things my gawd they are so tanky and fast and have unpredictable movements). The only thing that bugs me was the fact that enemies can spawn too much, overlapping one another, making it impossible to destroy an enemy that is gonna explode because that drone is just stuck underneath like, 20 other entities. But again, that is also part of the game's difficulty, you have to manage the horde so that it doesn't overwhelm you like that.
10/10!
