It has a good vibe and good feel. The gameplay mechanics are farily good, aside from a button issue (see below).
Notes:
- No pause button?
- Relying on shift as an active controller 'button' killed the game for me. Windows does not like repeated use of the shift button, which makes it next to impossible to launch an attack or even play the game due to the shear number of interruptions in gameplay.
- "You are dead" only covered the bottom-right corner of the screen during the boss battle.
