Ahhhh I said I was going to do Unity stuff, but was still in a concepting mindframe, so I went with that instead. Here's three tools from the explosives set.
Dynamite, your standard explosive.
The Crossblow! It shoots explosions out in 4 directions.
A Bomb. Covers more ground than dynamite, and the blast direction can be effected by walls.
Perhaps I'll lay out some floor tile action and start modeling some of that.
Have a good weekend!
