The game is fun, though I think that there are some places where it isn't very easy to figure out what to do, I didn't know how to kill the boss where the yellow symbols are in the purple and white areas. I currently have only not finished the boss fight in the purple area (4th image) because I don't know how to get it when it's under the floor the 2nd time, I have also only done 1 ending assuming there's 2 because the descriptions talks about a good ending.
