Really great NES feels for your game! The art is super cute (it's so good), and I think the curse mechanic you designed really works well with the gameplay. I'd be curious how your game would play differently with a few tweaks. First, the hitboxes on the enemies and traps feel like they're too big—I only needed to stand next to the spike tile to get hit and the flame enemies kept getting me even though I felt like I was clear or it should have been a close call. Second, I'd have put more contrast between your foreground and background tiles or maybe swapped the palettes—the bats became hard to read/disappeared into the grey background tiles whenever they'd fly into those regions of the level. Thanks for making and sharing your game—I had a lot of fun playing!
