Ascend the tower of puzzle boxes.
The Room Three is a port of a mobile game focused on puzzle boxes. You are presented with an object with a variety of puzzles to solve. The third in the series, it goes above and beyond to try and add new elements to the game (some good, some bad). One of the best additions is the little light system, adding new puzzle elements within already existing puzzles. There's also this central theme of a tower that you're ascending. This game takes a lot longer to complete because of multiple endings. Some are pretty easy to get, others are extremely difficult if you don't search for every nook and cranny. A first play-through is about three to five hours, but getting all the endings will take a long time. I don't really think the multiple endings add a lot, but they're there.
The atmosphere is the same as in the previous games. Like all puzzles games, sometimes you can get stuck. Though this was very rare. The most frustrating part is sometimes not knowing where the game wants you to look next. There is a hint system in case you really don't know where to go next.
It's pretty cheap in a sale, so if you enjoy puzzle games or escape rooms, definitely get this game. Despite the bloat of the multiple endings, the puzzles themselves are still great.
