Very cool game, nice level desing, i can see you worked hard on it, and you actually finished a good game, soft animations, several effects, several puzzle maps, and a complete finished product in a few hours.
In fact this game makes you play untill you finish it and you dont mind to expend time playing it, and that's rare for a gamejam.
But you didn't implement anything of the cursed theme, and that's sad. It reveal you have in mind to make this game, the theme didn't match what you expected, and you couldn't incorporate it to your game. Can't give 15 star sadly because i would like to do it.
