Really like the concept and idea that electrical energy can be absorbed and redirected against the enemy monster while being able to stored it as fuel for the slow motion effect. The lightning effect is really neat and I manage to fry a group of three enemies at one time. After playing the game several times, you should consider further develope the game in terms of the the attack system and maybe even turn the concept into a puzzle based game utilizing this attack mechanic. I would like to see more of it if there are plans for more development.
By the way, the main menu UI is really fantastic and is a good setup for your future games.
