Thank you much!
This was one of my first attempts at making a longer and more epic RM Horror game. While I like the final result, I reckon the game has many flaws and instances of poor game design, such as: innecessarily long corridors; lack of maps; lack of indications; badly designed health and sanity systems; the tiles collision bugs such as the one you mentioned, etc. Still, I learned a lot from this game and I really like the monsters (I like Helga so much I put her in A House for Alesa 3, so she's probably my favorite among the monsters I've created)
