New tileset allowing me to walk through walls

[Brendan Karou]

Hello! I have a small project I'm working on, but I had to create all my sprites from scratch.

However, the walls seem to be completely passable.

How should I fix this problem?

Check your TileB, the top left tile should be set to a star, otherwise you'll encounter issues like these.

Thank you very much! I must have removed it accidentally
