It's a decent game with a neat concept. The rewind mechanic and level design does need some work though. You can still shoot while rewinding and sometimes are sent back to somewhere you never went to. You can also kind of camp behind bushes and wipe people out or shoot people off-screen. Also because of the respawning it feels kind of repetitive shooting everyone and you can sometimes get jumped when a bunch of enemies respawn around you. It's decent otherwise though.
