Incredible visuals! The artwork was so well done, props to the artists!
The idea of adding bullet-time to a shmup was really cool. There were times where I felt like I had no choice but to take a hit even with the slip time activated but that's probably because I didn't destroy the threats early enough. Another idea I had during playing was that maybe the slip time mechanic can be a trade-off. As long as you're shooting it won't recharge so you have to stop shooting to get it back. That way the player has to decide when to be aggressive and when to be defensive. Just a thought!
Very cool game overall, had a lot of fun with it.
