I REALLY love the pixel art and the character design is great. It was really nice and atmospheric, I'd actually love to see a full game made in this style. A few points I noticed (I know you have addressed some of these in other comments already):
- It took me a moment to figure out what the control prompts were telling me to do at the beginning. The E looks like a C too.
- Monsters Pied font looks a little out of place, though maybe that is intentional.
- I kept getting killed at the second section and wasn't sure why, the spear wasn't hitting me.
- Meringue Mansion is an amazing name and now I've played the game it totally makes sense :D
