1 - Mega boulder. A boulder that is so heavy you cannot push it. Graphically it would be a round shiny ball of colour 5.
and
2- sloped mud. This would serve two functions: an aesthetic improvement to caves and creation of puzzles.
Sloped mud would come in four varieties:
/ - with top part filled with mud. This acts like a regular mud tile. Things can rest on the flat top without rolling off and it can be dug away.
\ - with top part filled. As above.
/ - bottom part filled with mud. This acts like mud, but items will slide off of it to the left if they can.
\ - bottom part filled with mud. As above, but the other direction.
The following ideas are less appealing to me and were an afterthought but still interesting enough to mention:
Sloped walls would be interesting but they already 'act' sloped - if there's enough graphics space it might be nice to have sloped variations of walls, perhaps just for left and right downward slopes.
Sloped titanium wall would also be interesting. Like a wall things would roll off of it, but it's indestructible.
I hope I explained that well enough. Anyway if anyone likes these ideas let me know
