Great pixelart and visuals (I love snowy trees with parallax background and the moon changing to eye when getting a curse).
The theme with a curse is also nicely fitting.
The enemy attacks aren't telegraphed really well though - they could get slow at preparation and flash/stand out more when dealing damage. Also the enemy patterns are unrecognisable almost as if random.
The combat screen takes a lot of time to close, but i suppose it's WebGL's fault...
