A cool idea, with a very fast paced gameplay.
It has some cool concepts, like the defeated bosses helping you on the stage stage until they are killed.
As a product of its era, it has some problems (like the red glow that happens every time an enemy is defeated, a trend that plagued games developed in OpenBOR for a while and thank God it was forgotten).
Who knows, maybe one day the author will make a revised edition of this game? :)
