@tobbi Hi! I was wondering if you could check my PR as a few weeks have passed since I opened it. I would also like to know what can I do for the 2 failing checks to pass. |

Can you please rebase against master? |
When leaving to the main menu, the game saves Tux's current worldmap position even if he is mid-path or on a non-stable tile. Upon reloading, Tux is restored to that invalid position. Save Tux on the last valid "stable" tile (such as a stop or level tile) instead of the current one. Also store the corresponding back direction to keep movement consistent after loading. In ghost mode, avoid persisting invalid tiles by falling back to the last valid level tile. This ensures Tux always respawns on a valid, navigable position.

Pardon?
In general, I would avoid declaring variables in if statements to improve clarity. Even with that in mind, it doesn't even seem like it is necessary in this case.

In fact, I believe this could be written in a more concise manner.

| m_last_stable_back_direction = m_ghost_mode ? m_last_level_back_direction : m_back_direction; |
Please make sure to double-check this logic.
