JUst played through the demo and WOOO! Seriously good FUN! Great movement!
I did notice using the pistol with the cointoss, you can jump, look down, toss a coin, shoot and 99% of the time you don't miss the coin. It really made bosses easy. I would just circle strafe, jump, look down, toss and shoot coins. I didn't have to look at the last boss in the demo to even kill it.
Loved every second I played and cannot wait for Early Access.
