This was a triumph!

So, after a long time trying to figure out how to make "grid" property work on Mari0, I finally found a way, and it was WAAAY easier than I thought. But now we have grid property! Ah, and, also, deadly property!

Lasers, light bridges, gels and portals can pass through...

OK, glowing effects because I was happy, but yeah, grids! Also, to set the "deadly" property, just add a pixel below grid's one. In order to make it work, for now the "deadly" tiles have to have "collision" set, but I'll try to figure out how to make them not requiring this.

But that's all I've got for today. I've made some small bug fixes on the "F1" thing but nothing really special. So, I see you in my next post!
