I'm not the biggest fan of rogue-lites but I'm a big fan of twin-sticks and bullet hells, and this delivers in spades. Learning enemy patterns can be overwhelming at first, but after sinking a few hours in, everything fell into place. The RNG can and will screw over several of your runs, but the game is heavily skill-based, so with enough practice the overpowered guns and crazy synergistic piles of passive items become unnecessary.
