Pretty innovative concept unfortunately not quite well exploited. The pace of the game is a bit slow, but that's just my opinion. I was a bit confused on how the secondary attack actually hurt enemies, oftentimes the fireball would just go through the enemy and go on its way. Definitely needs more feedback, it's not clear enough when we take damage or stop time. I liked the dialogues as well as the references.
Overall, goo job, this is a really solid base for what could be a great game, I honestly dig the whole stoptime-action mechanics, I really look forward to seeing more of it. (I think I focused too much on the bad points but really this is super cool)
