I just got this today (I know I'm late, I usually buy new stuff when it comes out, but I wanted the CE with shirt so it took some saving :p)
here's my 2 cents
-I like it a lot, plays and feels like stuff from days long gone, also it is pretty hard for newcomers to the shmup genre and there's a lot going on at the same time.
-Experienced no slowdown whatsoever, which imo is a good thing with shmups.
-As awlays with this type of game, plenty of replay value, better your own score & learn the combos
-too short (as always with shmups, though I can live with it, as there's quite a lot going on at the same time, so levels appear longer than they actually are)
-they should've given us a difficulty setting, this needed an easy setting as I think it is simply too hard for beginners, however it also needed a maniac mode, as I finished it in the first hour.
-still...as far as an indie shmup goes, I prefer this one over fast striker. well done on this one NG Dev
