Somewhere between classic and more of the same...
I appreciate the programming chops to make the slick environments and generate enemy skins and music on the fly, but all this randomness just amounts to a lot of variations around, well... more of the same. Not much new or exciting compared to most other bullet hells.
Acutally, played through more. the backgrounds rock, but the ships suffer from a serious case of what we in the "biz" like to call... "programmer art"
But yeah. Like the evolution system, it's different than the "grab the next biggest gun" scheme.
