Thank you for playing and for the thoughtful feedback! In all honesty, I did intentionally make it less linear, hopefully it wasn't too confusing.. and the tilesheet was initially intended to be completely solid like you expected. With more time, I'd have made a tilesheet that more clearly communicated the semi-solid instead of recycling a tilesheet from one of my previous games. As I'm sure you're aware, certain things just lose priority in Game Jams...
The story is definitely about parenthood and disability (not sure if your read the game description but that's legit in there!). Thanks again for the playthrough and kind words!
