No, by grass I meant these square tiles, restricting the whole level, which are too similar to ground ones visually. It seems to me that reading them as walls with "side looking" is very important.. And barrels/boxes: in any other case it would be just fine collision box, but here when you need to hide fast, it seems important to know at a glance where the far edge is. Although visually, seeng character dissapear behind it is kinda satisfying.. And of course you don't need to be sorry (lol you played my game - Im not sorry, no sir) :)
