Well, we know about the lame trick of getting across a floor of spikes by bombing yourself over or having an enemy hit you over the floor to get to areas you couldn't normally get to without lowering the spikes. Well, in a quest I won't name, but you all should know, that is being worked on. We make these spikes half solid in places we don't want you to cross and the rest walkable. So if you try to bomb yourself over, you'll get stuck on the solid portion but be knee deep in the spikes! good luck getting yourself out! XD

Creators should wise up to that trick and start using unwalkable spikes in areas they don't want to have players bomb themselves over, but keep certain spikes walkable for those poor saps that do try that.
