I really enjoyed playing this, the story set up was captivating and I liked all the optional power ups that require you to backtrack/go on a optional path, cornerstone of the MV genre. My only little gripe is that the character takes too much decelerate, making it feel like they are on ice. Especially with the first weapon with short range, it meant that many times when running and shooting their body would actually be in front of the projectile you just shot.
This by no means made the game not fun though, it's just that if I have to pinpoint one thing to improve on, it's this.
Unfortunately it also seems like the story was cut short, I was curious to see how it would develop further because the premise was definitely strong.
Overall it's a nice short fun game, I enjoyed it.
