相信不少游戏玩家会对自由观看游戏关卡感兴趣，在电子游戏关卡博物馆这个网站里，可以点击大量平台中的热门游戏，来下载其中的关卡到浏览器中，并在关卡内漫游查看。不过有些关卡似乎是没经过优化，可能在某些配置较低的电脑上存在卡顿的情况，这点需要注意一下。

I believe that many gamers will be interested in watching the game level freely. In the website of the electronic game level museum, you can click on a large number of popular games in the platform to download the level to the browser and roam through the level. However, some levels do not seem to be optimized, and there may be stutters on some lower-configured computers, which needs to be noted.
