Not very good, honestly. Movement is really slow and the game is really long overall, with 1cc remaining over an hour long. There are shmups this long that manage to keep things engaging, like Super Aleste, but such is not the case. At least the music is quite nice, although some loops are much too short for where they're used.

I had similar trouble as Angel_Arle with a boss around two thirds in. It wouldn't die under any circumstances, but when I used a continue and tried killing it without using the option, it worked just fine. No idea what that was all about.
