This was fun! Well done. The fights have some strategic depth to them. I liked it, it looks quite nice (though some of the text is a bit small). So the below is just things I think could be improved upon further:
I found the curses to be way too much. Major boons that grant you Fireball (3 AP) and +4 HP while also giving you -13 HP and -2 AP, resulting in less HP and an ability you can't afford to use feels like the game is making fun of you.
Couldn't make it past the Cyclops with the minor boons. Wasn't sure if the elite rat room had any purpose. And not sure if the wizard is locked for the jam, otherwise it should probably have been available from the start.
Not being able to attack diagonally while some enemies seemed able to was also a bit frustrating.
