Beautiful game, first and foremost. Great pixel artwork, I hope to see you hired by indie devs doing fantasy games, this artstyle needs to be out there.
Gameplay is simple and possibly due to that it's hard to see what the roulette is doing (could use a message telling you what effect is active and for how long, perhaps.) The witch is so strong, I don't know how you ought to evade those attacks and blocking doesn't reduce the damage enough to survive it more than once. But she's hot, so all is forgiven.
Minor things: Wish there was a stage select to skip to the boss that's killing me/get more practice against the witch and quicker. Wish there was a death animation or screen instead of such a quick sudden cut to start screen.
Got a bug where the knight was sent underground and I could just burn him freely, but he reset after a while. Don't know what caused it and what uncaused it, but might be something in the code for being hurt.
