This was genuinelly really fun! The sword swinging was satisfying, as was the blaster! I felt it was kind of a shame I couldn't one shot the small blue dudes with a fully upgraded sword, but it's okay.
The parry mechanic didn't seem very optimal - why would I parry their projectile, when it seems to do less damage than my blaster/sword and I can side step the projectile?
Only the reload of the blaster being tied to energy drain is really inspired and I loved that. Made the sword and blaster feel really distinct.
