Thank you! :)
I love breaking walls and finding secret stuff in games so I wanted to include that. I'm glad you liked the layout as well! I was not sure if my level design was good enough - although I myself liked it.
I was a bit nervous tho because since I made 8x8 tiles the "window, iron bars" tile is too dense to be able to look through clear enough to see the forest outside. I did not anticipated that when I started the development / made the art...and later I didn't have enough to switch tile size nor I wanted to scrap the 8x8 tiles.
