After 3 weeks I finally managed to create a new video about the accelerator block:
Like shown in the video the accelerator block can be used to speed other blocks up. In contrast to the conveyor-belt which is mainly used to transport resources, you can change the speed. But what's special about it is that it has physics which means that you can build inventions with it. You can place it wherever you want to (not like the conveyor-belt, which can only be placed on the floor).
The accelerator is the first block in a series of blocks that will allow you to create more dynamic things. Until now you could build different structures but the game was all more or less static. Furthermore, the next block that will find its way into the game will add a lot more possibilities what you can do with the accelerator and will allow you to build more complex machines which, of course, can also be used to defeat your enemy in multiplayer battles.
Hope you like the update, tell me what you think about it by writing a comment below :)
