It took me a few days to find all the effects but I'm really happy with my experience of the game. The fox mask was particularly tricky because I kept getting oranges instead of plums but it was also the most rewarding to go back through old areas and hear what their inhabitants had to say. I loved the art style and all of the different areas. The main character's different designs were very engaging and full of personality. You obviously put a lot of thought into creating specific moods throughout the game and it shows.
I encountered one glitch near the end, when equipping different effects pressing C would still activate the Umbrella's rain.
