I think this was the only submission where the player character was animated, although it might be a bit hard to notice due to the low contrast. Enforcing a delay before the trap doors "swing" open was rather sensible as it allows the players to use them as a bridge to get to the trap door on the opposite side.
Considering, however, the possibility that a player can find themselves trapped in a dead end, I think a redo mechanism would be a useful addition to the game. Also, you might be missing a sprite to represent a trap door when both sides have been opened..
Hope to see you in future game jams ^_^
