The game is very fun, very neat mechanic.
I do see a issue where if you get hit once, you WILL be hit twice in the final bosses as they have homing attacks that make you unable to dodge without your dash. This did make the last 2 bosses a fairly frustrating, but still have been a good time.
I love the shadow samurai boss, it does a great job at teaching the player to take their time in slow mo instead of attacking like crazy, really cool.
I would look up for a steam release with more content, really fun and does have room to get a lot better.
