A great game, pretty fun and challenging, good for people (like me) with a bit of patience... although the downside is that it can be a bit luck based due to the guard AI. Other than that, well done. :D
When going for the hard badge, I recommend warrior. It's skills are great, such as damage, defence and health, and with katana it is a powerhouse (and with Whirl and Sonic you can clear battles fast) and Blood Lust is great for tough enemies, just use it and use a health potion too and bosses go down fast.
A great twist on puzzle platformer games. I was going through the instructions, being bored as the usual platformer instructions came up, then the sign talking about the change of perspective came up and this became insta-favourited. Great work!
