This is great! I really love the physics based platforming; it is genuinely inspirational and I found myself wishing there was even more of it. I am not enjoying the combat as much right now. It might be a matter of skill on my side, or maybe it could be adjusted a little to feel more fun and satisfying. I do like that combat is included, and I can imagine the cube fighting other gambling themed elements, as well as elements of determinism.
I got to the place

Is there an ending I can reach if I manage to do combat? :) Got a guide or a video tutorial?
