When a developer works on a game on his own, he often has the opportunity to implement ideas that large studios consider too risky. The Twelve Boxes project, created and released by the author under the nickname pashooter in 2026, is a great example of this approach. This is a very interesting mix of genres where a logical puzzle meets a hidden object simulation and real psychological horror. At first glance, the idea seems very simple. There are twelve mysterious boxes in front of you and your task is to open them all. But what starts as an ordinary calm logic game very quickly turns into a real test for your nerves. The game does not scare you with cheap tricks or monsters, it scares you with the fact that you yourself do not know what to expect from the next box that you are going to open.
