This is outstanding Ikana, everything looks so polished and well made for a jam submission!
It really feels like a great blend of what makes breaking roguelikes fun, while still weaving in the theme perfectly, between the core gameplay loop and the majority of the items.
You've got a looping-eqsue system to get more powerful before taking on Immerred, and she's got a varied and deep move set and multiple phases? you did a fantastic job of taking all the mechanics that work from other roguelikes and blending them in here.
Its so crazy that you managed to get all this together, working, cohesive, and feeling good to play in two weeks' time. I know for a fact that Cece would have a blast playing this (here's hoping she does)!
You deserve top marks for this one, excellent work!
