Idea: In Hide and Seek, you select your block before your actually in the map, which can be problematic because if you don’t know the map too well and pick a block without knowing any specific spot then it can be hard to survive.
So I believe that during hiding time you should have a list of the available blocks for the map in your hot bar.
More information:
To select a block, all you must do is right click on the block you’re currently holding and you will become that block. Your block choice must be locked in before the 10 second mark, or it will auto-pick for you and you won’t be able to change it. Also the hiding time can be increased to 90 seconds to give players more time to find the perfect spot.
Feel free to throw out some ideas on this topic!
