Unappreciated effort, it appears...
While good as a bullet hell game, it seems as though some of the unique aspects of the game don't really get a chance to shine - there's too much going on to notice the enemy sprites or the variable soundtrack. The backgrounds were interesting and looked difficult to make, but wind up being either distracting or ignored. On the plus side, it is interesting to create a game that, by allowing you to take different evolutionary pathways, forces you to adopt different playstyles depending on the path you choose. One complaint I have is that the HUD display can easily get in the way, especially on later levels where you need all the dodge room you can get, but it's easy to get trapped behind the display and not be able to see what you're doing. Altogether a well-made game, but it seems like some of its features might be better used elsewhere.
