Hi, this is my submission for Assylum in the Gotham: https://shashking.itch.io/godmen
Description: You warp time to hit the enemies with their own bullets! Your black hole generator is critical so you can't time travel out of danger for long! Hold SPACEBAR to REWIND but if you hold it for a few seconds the black hole generator will explode! Reach the flags within time and finally cool your time travelling equipment in the RIVER!
