I'm just finishing my full replay of the game and now I realize how the dev was able to put out updates with a decent length.
So many reused scenes/images throughout the game. You don't notice if you play update by update. But replaying the game in full it is almost a bit distracting.
*Edit: Note I'm not saying what the dev did is wrong. They have rendered great quality scenes throughout their work. If they can shortcut render times by reusing assets, more power to them.
