Cute game!
Rotating curses is a fun idea albeit the ones in the game either change too little or make the current section impossible so you'll have to wait 10 seconds, so in execution they could've been better. Fav curse is darkness because it makes no section impossible but still has the biggest impact otherwise
There should've definitely been variable jump height depending on if you hold down or simply tap A once, like there is with most NES side scroller games. Maybe there also could've been some incentive to climb the tower quicly and not stand around waiting waiting for a less bad curse.
