Well, you could improvise for now. The grid would be cool, but you could just put blocks on the borders when you create a level to keep track of them (and yes, I know it's a small hassle, but you could do it for now)

There is a mechanism to make B bounce/jump, but you'll have to move it by yourself (B won't automatically jump when he walks on it). But if you're curious, here it is: http://mekoramaforum.com/media/tiny-jump-demo.3356/.

The electronic system would be nice, but I like the simple design of the game, and how you can still create great things. There are a lot of ball-activated mechanisms and such that are being used now instead of electricity.

 

I like the idea of a grid, although it may get in the way when working with 3-dimensional worlds. If I'm not mistaken, the limits are 16x16x16 blocks. But, yes, knowing where the corners of that are would help.

 

But bigger levels might cause a lot of lag on small devices (my phone already lags a lot when there are a lot of elements in a level). How much bigger would you like it, though?

 

Very interesting idea, but couldn't you separate the puzzles? People may actually get annoyed if it takes long to solve, as progress isn't saved in Mekorama.
