The giant footprint sprite looks wrong. It should be shaded a bit on the inner side to reflect the foot arch, currently it looks like she has planks for feet.
Otherwise fun silly game.
The timing on Mammon's double chain attacks is a bit inconsistent, the same movement pattern can save you one time but fail you the next. I think it's because the chains follow you, so they might end up in-between tiles so it still hits you.
Good game, will check again once the final version is out. Please get someone to help with the spelling and typos, because it kinda takes you out of the experience.
