Ah, yes, I do like myself a bit of bullet hell! This is a great use of time travel, at first I found it really hard to use effectively, but as your mind adapts to how the projectiles move through time in relation to you it gets more and more intuitive. I personally find it unwieldy that you can't shoot backwards and have to wait for enemies to pass in front if they come from the bottom of the screen, but it does force you to dodge and not instantly spawn kill! Overall great success, I like it!
