If Realm of the Mad God had Touhou hitboxes I wouldn’t have dropped it, but this is a damn good alternative.
The combo system is cool and the progression mechanic is solid. There’s something nostalgic about habitually activating all your skills as soon as they leave cooldown to eke out an extra bit of damage, probably from a childhood of playing kooky MMO games.
My one criticism would have to be the pacing of the game, as bullets come at you really fast, often with little warning. I tended to only have a small window of time to react so, I ended up never touching my favourite dash-mechanic.
