The two-games in one was a neat concept. I liked that not only was it a tonal shift in gameplay, but the palette was inverted as well - that's a nice touch.
I'm really into the wavy monochrome pixel design, but I did run into some trouble. I'm not sure if it was the intention but the dithering on the text made it quite hard to read. You can sort of make it out in some places, but in the roguelike section I couldn't read anything and had no idea what I was doing. Definitely a recipe for eye strain. Screenshot attached
Your cat seems to get into as much trouble as mine, really a true-to-life gameplay moment
Good game!
