shooting feels nice, and the pixel art style is cute.
disabling the players movement was not a good idea, it made combat feel really slow, and was more annoying then anything. It led to situations where I had to wait for enemies to come behind the corner when I rolled a 6 for example, or run around doing nothing when I rolled a 1.
slowing time is cool, but duo to the enemies predictable nature was not necessary, you don't really need extra time to asses the situation when all the enemies just move slowly towards you.
the music is awesome, and the sfx and particles are cool too.
great job on finishing a game in such a short amount of time!
