I tried out "Only One Door" a few days ago. To be honest, I was healed by its fresh style when I opened it for the first time. As a veteran player who has been bombarded by 3A masterpieces all year round, it is quite comfortable to have a change of taste occasionally. This game was developed by Hainan Star Jump Technology. It is free, has no in-app purchases, and is a purely casual game.
First, let's objectively walk through the evaluation dimensions:
In terms of graphics, the 2D simple painting style is really pleasing to the eye, with bright colors, no excessive light and shadow effects, and very low visual fatigue. The hand-painted texture is like reading a warm picture book. But after all, it is not a high-precision modeling, and the details cannot be compared with large-scale works. Give it a 7.5 points.
The gameplay is purely about jumping through levels, clicking or touching to control the character, and there is almost no learning cost. There are some clever ideas in the level design, such as using a sense of rhythm and predicting timing, but the overall difficulty is low and may feel monotonous after playing for a long time. Suitable for commuting on the subway or waiting for takeout for a few minutes. 6.5 points.
The krypton gold is directly 0, and there are zero in-app purchases and zero ads. This is so conscience-breaking. There are very few free-to-play games in the current mobile game market that can be so clean, so good reviews. 10 points.
There is zero social aspect, no rankings, no friend system, no online elements. Completely single-player, suitable for players who like to be alone. This is not a drawback for casual gaming, but if you want a lively competitive atmosphere, you may be disappointed. No scoring is done and ignored by default.
Overall, it gives a score of 7.5, which is “recommended to specific groups of people”.
Taking this opportunity, I would like to talk about how to evaluate game ratings. Many people think that a high score must be a masterpiece, and a low score must be a scumbag, but my point of view is: the score is never an absolute value, it is the weighted result of multiple dimensions such as game type, audience positioning, completion, and innovation.
For example, "Only One Door" has a high degree of completion in the "leisure decompression" segment: comfortable graphics, simple operations, and no hassle. But it would obviously be unfair to compare it with "Elden's Ring" for operational depth and "Genshin Impact" for social gameplay. The scoring criteria should be based on the experience the game itself wants to give players - if it wants you to relax, then see if it is not anxious, irritable, or forced. It does this very well.
In addition, the proportion of graphics and gameplay also varies from game to game. For action games, feel is the soul; for narrative games, plot is the core; for casual games, comfort and fragmented time utilization are the key. So there is no unified answer to the matter of "fun".
Back to "Only One Door", it may not keep you playing all night, but it will allow you to steal a moment of peace in a busy day. If you are usually stressed and just want to find a mindless game to relax yourself, then it is worth a try. But if you are looking for excitement, competition, and in-depth strategy, it may not satisfy you.
As for my final score for it: 7.5/10, the reasons are as follows: +0.5 for comfortable graphics, -0.5 for simple but not playable gameplay, +2 for completely free, and no points deduction for lack of social interaction. The upper limit is not high, but it is well within its positioning.
