Peak overstimulation core. Exactly the kind of game that the new generation needs.
The gameplay is good. The fact that you have different "builds" with bullets and gravity weapons allows for replayability. The gravity weapon design is very innovative. Charge up a powerful weapon, at the risk of making bullets home in on you. If I was better at bullet hell games I'd probably enjoy it more.
The sound design is excellent. The visual design, while janky, is very cute and charming.
